PS3 has the Move, which is pretty darn sweet I might say. Haven't read much about the Kinect, and I think it is a neat idea, but there are no buttons! That really limits what you can do, like no arcade shooters.
I think the systems are pretty equal, each have their pluses and minuses, and there is not a clear winner in the eternal debate of PS3 vs XBox as it comes down to personal preference.
I'm into home theaters so I love that the PS3 has blu-ray, and consider the orig XBox 360 didn't even have built in HDMI (WTF). They didn't even include built in wireless until the most recent XBox release. So at the time I made my purchase the XBox wasn't even a decision as it didn't have HDMI, wireless, and you have to pay to play online.
