Well here's a pleasant little surprise. Rockman 9's status of being a Wii exclusive title in Japan is no more; the game is off to XBLA this June. According to a press conference in Japan, Rockman 9 will join the ranks of 30 other games coming to the console in 2009.
Not much else to say than that :)
UPDATE: Famitsu reports RM9 is also on it's way to the Japanese Playstation Network.
