The Wii has been on the market for at least two years, and yet neither the US nor Japan has seen a VC release of any RM/MM title.
Who's to blame?
Don't point your finger at Capcom, gaming behemoth Nintendo is the real villain here.
According to Capcom's Public Relations Director Chris Kramer, Capcom is only responsible for licensing the rights to their games to Nintendo. Thus, it is up to Nintendo whether and when MM/RM titles get released on the Virtual Console.
Rockman isn't the only one getting held back from VC releases. Countless other titles from both first and third parties have yet to see a VC release. Chrono Trigger anyone?
It's possible Nintendo has some fancy schedule thing, releasing certain titles only at certain times. Then again, maybe we're just getting screwed.
Only time will tell.
