Sony have been consistently saying that, when it come to the PS4, they won't be making the same mistakes as they did when it came to the PS3, particularly regarding costs.

Addressing analysts and investors during a financial call this morning, Sony chief financial officer Masaru Kato said that because Sony are not starting from scratch this time around, in terms of developing hardware architecture, the amount investment required is "much lighter" than before.

Sony Worldwide Studios boss Shuhei Yoshida has said that the company is "not crossing out any type of game" and, moreover, has started developing an as-yet unannounced free-to-play title.

Sony Worldwide Studios President Shuhei Yoshida has once again reiterated that not only will the PS4 not require an always-online internet connection, but that the Japanese company never even considered it.

A new report has emerged suggesting that Sony might struggle to meet their expectations for shifting 12-16 million PS4 units in 2013 as supply chains are yet to receive any sort of shipment instructions from the company as yet, thus potentially pointing towards a delay when it comes to the console's mass shipment schedule.

Spoilers are terrible things, and with the integrated "share" functionality giving players the ability to seamlessly share the things that they do with the PS4, are Quantic Dream and David Cage a little perturbed by the thought of having unique experiences compromised by such a feature?

Not a bit of it. In fact, Cage is rather excited at the prospect of a built-in metaphorical water-cooler.

Remember the infamous Killzone 2 reveal back in 2005? It was supposedly real gameplay footage, but it was actually a pre-rendered video designed to showcase what the PS3 might be able to do.

In any case, for the PS4, Guerilla Games decided (probably for the best) that they really ought to make the reveal real.

Several Sony tech developers have released a video all about the DualShock 4, the PS4's flagship peripheral. It's cloyingly smug and self-congratulatory to a fault, but does gives you a good idea of the size of the controller, as well as some of the inspiration behind its design and feature set.

Sony Worldwide Studios’ vice president Michael Denny has reiterated that Sony are trying to present a console "absolutely focused on gamers", and that the company have learned lessons from the release of the PS3 (which launched at an exceptionally high price point of $599).

Denny didn't go into huge specifics,, but whilst on the subject of pricing he hinted heavily that Sony are doing their best to make the new console affordable.

Wants all sorts of games, not just FPS

Sony's Shuhei Yoshida has gone into some detail regarding the structuring of the PS4's February reveal, and what it means for the console and Sony going forward.

He said that by leading with Knack, Sony were showing that they wanted a wide range of games, not just FPS titles, and reiterated that of the the five key principles upon which the PS4 is being built, none off them are hardware-related.

"It’s Like Giving You The World’s Best PC.”

Epic Games have been quick to jump on the PS4 train with Unreal Engine 4, suggesting that Sony's new console is akin to the "world's best PC."

Easy now, fellow PC gamers. Easy. Let's hear him out first.

DayZ creator Dean Hal has suggested once again that a console version of the standalone game is "almost certain", just as long as it doesn't screw up the PC version, that is.

Infiltrator & Elemental

Epic Games have released two tech demos of Unreal Engine 4 doing its shiny business, both on PC and PS4. Both real-time videos demonstrate the new high-end rendering features and tools that will doubtlessly play a key role in numerous next-gen multiplatform games over the coming years. Check it out below.

"Sony is really in to win this one"

Sony have already dealt an early hand in the battle for next-gen getting the jump on Microsoft with their February PS4 announcement and placing the emphasis fully on gamers and developers, showcasing hardcore gamer services (social, streaming, and more), and a refocused commitment to indie development.

The whispers coming out of GDC suggest that Microsoft has a very different outlook, and that Sony are pushing developer relationships decisively with an eye towards nothing less than "winning" the next console generation.

Geomerics, a game tool design company, has updated their real-time lighting tech to take advantage of the PS4. According to the founder and CEO, Sony's upcoming console allows them to develop without current-gen "compromises."

UPDATE: Geomerics have released the (more spectacular) second part of the tech demo, which we've embedded after the break.

We're yet to see a price or even the physical console itself but we can now see what the day-to-day menu screens may look like. The screenshots Sony have just released show a selection of screens that have a heavy emphasis on the social side of gaming. The image above features many tiles informing you of your friends’ activities such as purchases or in game achievements.

Player profile screens have been spruced up and now feature photos and real names of players for the first time. We imagine you'll be able to tweak the privacy of these features. We can also see what may be the screen that appears upon pressing the new Share button in a menu asking if we'd like to share a screenshot or video, there's even a screen showing a video trimming feature.

Sony are looking to hook up some of the features to your tablet and mobile device too as shown in other screens. You can see all of them after the break. You can click them to get a full screen version too. So, what do you think?

In this week's Game Buzz we kick off with a look at the love that the PS4's been getting from certain quarters, including apparently making Suda51 "horny"; we have a gander at the Xi5 Piston saga and the divisive price point at which it's been placed; we ask if Call of Duty really has ruined a generation of FPS players; we discuss whether or not we'd like to see a third game in American McGee's Alice series; we chat briefly about the God of War trophy controversy; and Jon delivers his verdict on the Army of Two demo.

World Of Warcraft lead systems designer Greg Street believes that making MMOs work on consoles would be a "huge challenge," but an opportunity that Blizzard are excited to explore.

"I've had a bad time working with Microsoft in the past"

Having Jonathan Blow leap onstage to present The Witness at the PS4 unveiling was something of a big deal for Sony, a move clearly designed to present the notion that the platform holder is serious about luring more indie talent to their next gen console.

As for Blow, well the choice was simple. After all, he's never been particularly fond of Microsoft an their treatment of indie devs.

Oh Suda. Never change.

The studio behind Just Cause reckons that the PS4 marks a much-needed step forward in console horsepower, suggesting that Sony's next-gen offering will remain much more powerful than the majority of consumer PCs during its life cycle.
