It's another instance where digitally stalking members of the games industry pays off. In a recent tweet, Ippo Yamada made this comment:
Presenting a soundtrack project summary. I must get to writing it up.
Of course, there's no mention of this soundtrack having anything to do with Mega Man, but honestly, I can't think of a time when a soundtrack from Ippo HASN'T had to do with Mega Man. Plus, the fact that Ippo has to make an project outline for it (presumably to get approval) would indicate it's based on an existing property. Well, I suppose it could be a Gal Gun soundtrack... if that game even has music over the squealing girls. We'll just have to see.
