The Shattered Memories screen isn't 850x480. It's smaller. It could have been cropped, or it could have been poorly shrunk. Until we know, I can't take that screen at face value.
Also, the stuffed bunny in the Homecoming pic has wierd lighting. Plush material should not reflect light like that. I could understand not having "plus shading" on even the HD systems yet, but it looks like it's made of ceramic in the picture.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
Plus, just for the hell of it: Kelly Brook at the 2008 BAFTAs
