Capcom-Unity has revealed the release dates for all three systems, as well as the 8 Weapons your Rock or Blues will be receiving when they teach those Robot Masters to respect the ways of Justice, Peace, and Yellow Scarves.
You could simply follow the link above, or I can just tell you. Either way, you win!
WiiWare = March 1st
PSN = March 11th
XBL = March 31st
Of course, this clearly means that Nintendo wins the Console Race, for the first to have Playable Blues wins EVERYTHING!
Secondly, the Weapons.
