Surprisingly, Sega just trademarked Cosmic Smash in North America. The original game was released back in 2001. Why would Sega trademark Cosmic Smash? Could they be working a new Cosmic Smash game? Perhaps, for the Wii, which seems like the obvious home for such a title?
A wiiware version would be cool but I think it would be better on XBLA since you would probably be able to use your own music and ave better highscore boards
