And it's soon. :P September 22nd for WiiWare (Monday!) 25th for the PSN, and October 1st for Xbox 360. I'm so glad I set some Wii points aside for it. :P It's going to be great.
Also, at least one bit of DLC is confirmed. Protoman will release in October for $2. He'll be able to charge his shots and slide (which Mega Man can't in this game) as well as block bullets with his shield.
