Capcom has said that it is still committed to the Mega Man franchise, and it plans to reveal new games in the series "in due course".
Speaking in an interview with Game Informer, Capcom US boss Christian Svensson said:
"Change has been a constant during my six years at Capcom (vastly for the positive) but I want to be crystal clear on this point," he said. "Mega Man is a key brand for Capcom and will remain so. I don't have any products we've announced publicly that I can point to and say 'see, I told you' but there are 'top men' ('top men'? 'Yes, top men') within Capcom thinking about the future of the brand and where it's going.
"We will have official announcements in due course."

Mega Man didn't appear in Ultimate Marvel vs. Capcom 3's expanded roster, and the publisher aborted a proposed 3DS project, Mega Man Legends 3, leaving some long-term fans of the series alienated - an issue of which Svensson is well aware.
"This is absolutely an issue that keeps me up at night. Unfortunately there are times that we have to make decisions that don't make sense to the community and the fallout, while understandable is regrettable. Our relationships with fans are extremely important and I know we've got some that are disenfranchised right now.
"Unfortunately, in this situation, there is no panacea. It's going to take time to rebuild those bridges. Product cycles are long and it'll be a little while until fans can see the light at the end of the tunnel. And the last thing I want to do is prematurely announce something in the name of sating the fans that gets cancelled or redirected later, thereby creating an even larger wound. I can only ask for people's patience.
"In the meantime, we're going to be stepping up our community engagement efforts in the West."

From what I read, I doubt that any new MegaMan game to be announced in the next few months is MegaMan Legends 3. It could involve the Legends series, but I doubt that they'll revive Legends 3 directly any time soon. However (And hopefully), I can be wrong.
