I've always preferred rl night footie to day footie (adds the danger component to the shot). I think they should incorporate Kinect technology ONLY in the Create-a-Skater setup of your character. For real skaters, being able to mo-cap your own style for tricks would make your character ENTIRELY unique to you (your ollie style, flip tricks, etc). After that phase though I prefer playing with a controller because the flickit system is fantastic.

Only other suggestion would be to make a HUGE engine like a Liberty City from gta4. It's been suggested a thousand times but the replay value of that game might stretch to a half decade (easily). This may require a new console with the capability to make every single object in say Liberty City grindable (this would take months to maybe years for the development team to achieve which would put this kind of a game 3-5 years away, which, I'm cool with
