I'm a little surprised news has been slow to trickle out. I'm also surprised you forgot to mention GRAW2; I'm seriously excited about that title and can't wait to start the new multiplayer campaign.
There has been numerous references to what Sony may have in store. Something of an acheivement and Mii channel from what I gather, but its hard to say. Rumors are also rampant about the introduction of a new Sixaxis with rumble features.
News on the Nintendo front has been really quiet. The Wii is awesome and I seriously love it, but it's lacking a steady flow of worthwhile titles. Everything is either a firstparty Nintendo title...or a thirdparty port of some other title revamped for the Wii.
