With the original PS3/360 version available for around £20, re-releasing the PS4/XO version at full price+ seems a bit cheeky to be honest. Most retailers have pre-orders around £45-£48, but Green Man Gaming will send you a copy for £38.99, making it comfortably the best pre-order price around ahead of the November 18th release date. Expect better visuals, extra radio material and extra traffic on the roads (because that'll be fun). At full price, you should only be considering this if you didn't play the original. It's worth noting that other new-gen remasters like The Last of Us and Metro Redux appeared not long after launch for around £25 in numerous online sales.
