Definitely, The Last Guardian. Glad that other posters brought it up. A game that I want to see would be a Zone of the Enders sequel. I mean I've only played the demo for the first game, so the series might pertain more to trappings that would cause a falling out for me, but it definitely had the makings of what I would call an ideal game. That and a MegaMan Legends sequel.
As far as the choices go, Twisted Metal would be my pick (loved 3;something I don't see often, but wasn't crazy about Head-On;PSP port probably didn't help).
