E3 games I'm interested in...

One game that I hope turns out good would have to be Army of Two. I like co op games, playing a video game with a friend along side you is just more fun then the usual one player mode. I noticed that Adam and Morgan from G4's Xplay really like Call of Duty 4, me I've never been into the Call of Duty games. The only Ps3 game I even care about would have to be MGS 4. I still don't have a ps3 and really don't want to spend 600 dollars for one even if it comes with motorstorm. I could use 600 dollars for many other things like, car maintenance, gas, and some more xbox 360 games. Halo 3 looks interesting even though I've only recently started playing halo and halo2 so I'm not up to date on halo.
