Alright, it finally got here and my first impressions was that the controller it self has a great feel to it.
It seems really durable, nice grip and a nice wrist strap which I doubt will slip off or break like the Wii.
I played Tiger Woods with it and you have to have a pretty good golf swing with good follow through for it to hit right, I would go as far to say that it's a simulator, which I like. It picks up amazingly and has great registration.
I then went on to play sports with it like Table tennis, and when I went to calibrate it, it didn't calibrate at all. I had to go the the PS menu and calibrate with system configuration, and that solved it. I guess it's not really a problem considering I didn't set it up that way to begin with, but a few other people have had this problem as well.
When playing a with this, you'll need a good bit of room, about 8ft away from the TV or camera. Not a problem for me, but could pose one for other people.
When I was playing table tennis, I got into it a lot, because it seemed that the slightest movement of your wrist would cause a spin on the ball making it seem a lot more realistic. It also registers speed which made me want to play it a lot more, because it was gratifying getting a nice slam.
Other then calibration problems which was easy to fix, I think that it's a great item. It's definitely better then the Wiimote, but I'm not sure how it stands up to the Kinect, as I haven't played it at all.
I would recommend this to whoever has a PS3.
