I will play rising no matter what but walker is the one I'm looking forward to since Kojima is directly involved and you get to play as Big Boss.
I'm a Sony fan but I don't hate on people for being XBOX fans because I feel bad for them. The machine has been a disaster from day one with all the technical problems (e.g. The Red Ring Of Death), plus the fact that they still charge for XBOX live. The fact that the thing has no built in wifi is like a kick in the teeth. I don't think the 360 is just going to wither away and die because of the limited storage capacity of DVD9, but at the same time what will Microsoft do when a developer says...
I love GTA on my DS. The game is not going to be good on PSP at all and that's a fact since all the best parts of the game deal with the touch screen. Rockstar needs to bring us San Andreas Stories. I personally liked VCS better than GTA4 because it had all the goofy characters and campyness that the series is known for. But whatever, I'm not going to waste my time or money on the PSP version.
