While we're still being fed from the rumor mill, it's pretty much established that there's a new Mega Man project on the horizon. Capcom filed trademark for "Mega Man Universe" not too long ago, and a PDF on Capcom.jp outlining their business plans for the next year references "Mega Man Online" in their plans to expand into the online market.
I'm sure you guys know by now that I'm a huge Mega Man fan, so it goes without saying that I'm excited about this, whatever it ends up being. The speculation has ranged from MMOs to fighters to yet another crappy EXE series, but it's starting to point to the MMO prospect. It's being produced by Neowiz, a Korean MMO producer, but that's really all that's known right now.
To make things even more interesting, a promotional image has popped up, implying that it focuses on or at least involves the X series. I always envisioned an X MMO involving players making their own Reploid character and choosing a side with the Hunters, Mavericks, or outlaws, but seeing X featured prominently makes me wonder what exactly they have planned. There's a chance it could just be a crappy browser MMO, but I've still got my hopes up...
If the image isn't fake, then it's interesting to note that (1) X isn't on Earth, since Earth appears to be that planet in the sky, and (2) the art style is very round, like X4-X7, but with the proportions of X1-X3's art, which I really like.
