The above is concept art of Roll for an upcoming Nendoroid figurine. As you might notice, the design isn't really Nendoroid in style. Nendoroid figurines are usually much more chibi in their design. This is leading some to believe that this redesign of Roll is actually part of something bigger going on with the Mega Man franchise. All I can say is that I certainly hope that's the case!
Megaman 11 confirmed, with Roll as a playable alternate character (why not, she was playable in Megaman: Powered Up).
