I've got a Kinect, and it's awesome. No controller, which is great, and the games are getting really cool. You do need a lot of space to play, so keep that in mind if you've got a tight living room.
TS4 is alright, I liked TS3 a bit better I think, but I'm hoping that Grand Slam 2 from EA is the answer for me. I'm waiting for a deep career mode and more realistic gameplay...Here's hoping.
