In fairness, MS were fantastic yesterday. It was just brilliant announcement after brilliant announcement. The Project Natal thing is obviously a gimmick (as much as the Wii is) but it looks like it's mildly entertaining at least. Alan Wake looked incredible, as did Halo: ODST (I've never played a Halo game before, though!). And, of course, MGS: Rising (do we know if this is exclusive to the 360 yet?) is extremely appealling.
That said, I'm always going to be a PlayStation fan, I think, so I'm hoping Sony will deliver as much as, if not more than, MS did later today. A re-designed PS3 would be a great start! They should give lots of time to Versus XIII too, which I think will sway FF fans who have yet to buy either a 360 or a PS3 (like myself). L.A. Noir, White Knight Story and Heavy Rain will also be awesome :]
