It's hard to gauge if I'm more excited about the Nintendo or MS games, probably the Nintendo games but I really want to play the Kinect games. I've looked at the games announced at the Sony conference and they range from don't interest me (Killzone 3, GT5, inFamous 2, ect), I don't want 3D with glasses, and at the moment I have no desire to spend $150 on a Move.
