As we all know, Bluefin Tamashii Nations and Bandai like their polls, including those which tell them what Mega Man fans want from the seven different series and their respective casts which comprise the franchise. They've gathered information via Facebook as well as the New York Comic-Con, though the latter may have presented a bit of a snag for many of the Mega Man Legends fans who voted on Facebook. When chatting on the Preorder66 podcast (18:50 in), Bandai's Adam Nemwman said that the company had believed that there was a tremendous demand for Mega Man Legends, with Facebook voters specifically calling for MegaMan Volnutt and Tron Bonne, but their poll at the 2012 New York Comic-Con told them another story. There, he says, response more strongly favored Mega Man X. He adds that the company still wants to do Legends, but that for now, those plans will have to be delayed.
For what it's worth, they say they still want feedback on Facebook, though we can understand how a statement such as the one above might make some skeptical. However, Nemwman also pointed out that their Mega Man products make up 80 percent of Tamashii's sales in the U.S. alone-- stronger here than in Japan, no less-- so that might give them plenty of reason to pay attention to that Facebook feedback.
Finally (for the Mega Man stuff, at least), they're still undecided about releasing the Sigma D-Arts mock-up they showed off at the San Diego Comic-Con. They know people want to see him in fully-articulated glory, but they're still working out the finer mechanical points to see if they can do just that.
