Keiji Inafune and crew have yet to deliver Mighty No. 9 (it's still a long way away), but its massive Mega Man fanbase has jumped ship, and is already wanting multiple Mighty games.
Last weekend at SGC 2014, fans asked Inafune if a Mighty Legends (a game based off Mega Man Legends) was ever in the cards, to which his translator gave a coy response -- "he's got nothing to announce today, but the fact is, he's heard all of you shout out like that. He's definitely putting that in his pocket and taking it back with him."
I sure hope Mighty No. 9 arrives smoothly on all the platforms they promised, or there's going to be one angry legion of fans ready to strike back.
