RUMOR: Jet Set Radio 2 on Gamecube
Take this with a grain of salt.
Please note that this is tagged as rumor since Sega has yet to make any official claims on the subject.
A little over a week after the announcement that Jet Set Radio would be showing up on Gameboy Advance, reliable sources are hinting that a sequel to the Dreamcast original, based on the canceled Jet Set Radio 2, will land on the GameCube. Unlike Jet Set Radio Future for Xbox, the GameCube Jet Set Radio will return to it's Dreamcast roots, providing a much more challenging experience which many felt was lacking in it's Xbox incarnation.

I'd love to see a more direct sequel to JSR, but I hope Smilebit also implements JRSF's lack of time restraint. Maybe there could be two modes: Story mode and free-roaming mode, for when I just want to skate & grind aimlessly.
