Well, THIS just came out of freakin' NOWHERE. ...OK, so there was one vague hint at the end of Mega Man Issue 40 (where Xander Payne draws a picture of Sonic's head on the walls of his jail cell), but I didn't think it'd point to another crossover (Wily doesn't remember Worlds Collide, Eggman couldn't possibly be so stupid as to try using the Genesis Wave again, and the Genesis Wave itself is no longer a secret to Sonic and co.). And indeed, the reboot, at this point, is already established; why would they want to reverse it now???

Anywho, what I suggest they do is include the Freedom Fighters and some of the comic-exclusive Mega Man characters instead of using only game characters like in Worlds Collide. ...Then again, with Ian Flynn writing the story, it's pretty much impossible to predict what'll happen in this new crossover (he's just full of surprisies, isn't he?).
