Rewatched the MS presser again (missed some parts earlier). Showed some impressive exclusives. Still not sold on the motion thingy, and I agree with what jer said. Totally depends on how MS pushes it, pricing, and 3rd-party support. If all we get are Wii-ports, then I can't but think it will fail.
I do think MS presser will be hard to beat. Maybe if Nintendo comes out with guns blazing and shows some new Mario, Zelda and other hardcore-centric games and cuts out the casual crap, maybe. But I doubt it will be enough to get me excited and wanting to buy a Wii.
I'm not really expecting too much from Sony tho. God of War 3, and maybe some FFXIII (and Versus) news is all I'm really wanting to hear about.
