Mega Man 9 is slated for a time exclusive release schedule. Wii gets it first, then PSN and last but not least, Xbox Live Arcade. Here is the schedule:

Wii Ware – September 22, 2008
PSN – September 25, 2008
XBLA – October 1, 2008

Looks like Nintendo and Sony are finally buying some timed exclusivity rights. We’ll have a review of this game in the very near future.
