I'm not ruling it out. Nintendo has been on a roll lately with reinventing entire genres. Splatoon, I mean, who would have thought that game would be such a great competitive shooter!? Arms seems to go completely south of traditional fighting games much like splatoon went south of games like Call of Duty. As a gamer that craves new content, I really appreciate this.
The idea of changing arms on each...arm...is kinda cool. I just hope there's more weapons to get, more characters and stages. And maybe an Arcade mode or something. Online should be fun as well.
