I've had issues with SONY hardware since the 80s when I had to replace a new Walkman 3 times in one month, after which I got some no-name portable cassette player which lasted me for over 15 years. I bought a PS1 and very soon had to start turning it upside down to get it to play games. I didn't get a PS2 until a couple of years ago, and I got it to replay a couple of old PS1 games and Fire Pro Z - now it's mostly made of dust and cobwebs. Never got a PS3. But I've played the heck out of my 360...
But currently it looks like next gen I'll be picking up a PS4. I'm not wholly against DRM, but I'm principally opposed to the particular brand of it Microsoft is trying to foist off. If it didn't have the 24 hour time limit I would be somewhat less annoyed. And then there's the whole shoving-the-Kinect-down-our-throats thing, which is the main killer for me. And it doesn't matter if it can be turned off. I don't want to buy it, and I don't want developers to get comfortable with the notion of forcing Kinect functionality on me in their games because everyone is forced to have one.
Nintendo... actually got me slightly interested in the WiiU. Mainly because of X, though I found myself kinda wanting to play that Mario game and the new Mario Kart. And Wonderful 101 sorta got my attention.
But beyond the hardware, other than a couple of Nintendo exclusives, I think the majority of the games I'm interested in are multi-platform.
