There's an idea going around that the Mega Man 10 bosses could be references to other Capcom properties.

Sheep Man:

for Flock:


Commando Man:

for Bionic Commando (the good one, anyway):


There's really no hint that they actually are referencing other Capcom games with these bosses (the only two revealed so far), but it would be both awesome and hilarious if they did. I can imagine a Lawyerman, Zombieman, WarTimePhotographerman, HoboMartialArtsman.... they have a lot of games.
