So let's start with the most improbable thing going; an in-game E3 demo that also ends up as something in consumer's hands before the year's end. Needless to say, a proof of concept is desperately required to quell many fan's fears, as so far the only thing shown has been a tech reel of sorts last year, although all that consisted of was a shot of the world in-progress, a Krogan-looking alien and plenty of voiceover about how there'd be an entire galaxy of possibilities. Obviously it was early days and they wanted to test the waters, but that was then and this is now - if the team have been hard at work putting something together it means they've at least got the concept for the game's direction nailed down. So why not show off what they have? E3 is the place for big things to arrive and blow people away, and all eyes are on this year especially to deliver something monument for everyone to get stuck into.
