On this gen, I just bought the 360 few days after it came out.
I liked PGR 3, and I wasn't expecting nothing on PS3 so I didn't want to wait.
Then amazing games went out like Dead Rising, Mass Effect, Oblivion, Forza, Lost Odyssey, si I knew I made the right choice.
But this console has too much drawbacks. The RROD issue, that struck me twice (hopefully the warranty was still valid), the Live that should be free, I kinda boycott it, thus I mainly play offline games, and now since MS released Kinect, they completely gave up on the gamers. It's like they don't care at all.
Recently I saw the new Kinect feature : being able to share the advertising on Facebook, Twitter, ... with a vocal command. So now we're doing their advertising job and we're paying for it?

They're trolling us right?
But anyways, I'll still be playing with my 360, I have quite a lot of games to start so that I don't need to buy another console.
And I must admit that there are some PS3 exclusives (Uncharted, Heavy Rain, some JRPGs) that make me think of buying one, but I don't want to invest on a new system. I'm fine with my Xbox.
