The next retro adventure of Mega Man, Mega Man 10, was initially revealed as a WiiWare title. That doesn't mean that it's a WiiWare exclusive.

The latest issue of Famitsu (via Kotaku) states that MM10 will be released through PlayStation Network and Xbox Live Arcade as well. Mega Man 9 hit all three platforms so this was expected. Nice to know for certain, though.

MM10 is a 2D side-scroller like its predecessor. It adds new levels, lorded over by strangely named bosses.
