Found a strategy guide for this the other day. Looking through it, it looks like Tron, Sam, Quorra, and Clu suits are all included on the game disc. All of them have discs-on-a-stick, but there are also Jules Verne books, lightcycles, and recognizers.
On a stick.
EDIT: Just saw MasterCylinder's post. He appears to have beaten me to it.
