That's pretty much the whole story in the headline there. UDON Entertainment is planning to announce their biggest ever Mega Man project next week. And as a means to build the hype, they are releasing pieces of an image each day until then. The first of five, which looks like MegaMan Volnutt, is up now. Or... maybe it's X without his helmet, though I'm not so sure there. Perhaps the future image reveals will continue a Legends themed product, or perhaps reveal other series entirely?
Commence the five days of hype and speculation!
