I got to play it for a few minutes...I'm definitely going to get it.
The control is odd, but actually pretty good. You rotate your skater with left/right, up is to accellerate, down is to brake.
The cutscenes are basically eliminated, replaced with static images and text. Voice is greatly reduced. But the first song (training levels) was pretty good...not sure how many songs there are.
Even though this isn't true 3D like Super Monkey Ball Jr., what the devs have pulled off here is impressive.
