It's similar to the Wii.
I played a few frames the other night after downloading. Seemed decent enough. Didn't have time to go through the tutorials so I'm not sure I was doing it right. I did have 3 strikes in a row, though.
Spin is done with buttons on this one.
Also, any music you have on your PS3 is accessible during the game. I believe that's a first. No streaming from your PC in-game, though.
