If you haven't already pre-ordered Mass Effect 3's N7 Collector's Edition, chances are that you've missed your opportunity to get your hands on the swag. BioWare's Chris Priestly has confirmed that no more physical items can be made in time for the March 9th launch, despite fan pressure to increase production.
“Sorry, there simply cannot be any more physical CEs made before launch. The items included in the physical edition cannot be made in time for launch. Sorry, it will not happen. This is why, back in November, I started warning people that the CE would run out.”
GAME has a few of the PS3 and PC versions remaining at a comparatively reasonable £59.99 price point, but otherwise, it's slim pickings unless you're willing to opt for the digital edition. I daresay that some of you managed to take advantage of Bee.com's (now expired) £14.99 pre-order for the base game.
