Hmm... I'm not sure whether this sucks or not.
On one hand, Megaman games are fairly reliably fun. On the other, this game didn't really seem that great. I've heard it had control issues.
Plus, it doesn't look like it was coming out on the Wii. I'm not a Wii fanboy or anything, but I can attest that the Wii Remote on it's side is currently the BEST way to play Megaman games. It just feels closest to the NES. The PS3 and Xbox controllers just feel to bulky by comparison, especially for such a simple type of game.
Maybe its because Inafune left, maybe the earthquake/tsunami/nuclear reactor thing, maybe they felt like focusing on Legends 3, maybe they decided it wouldn't be that great, or maybe this is all a big April Fools prank.
Whatever the reason for this announcement, I won't be losing any sleep over it. (but if it really DOES come out, I'd probably still try it)
