Don't forget this new game is not a sequel. Sakurai originally left Nintendo because he got sick of always making sequels (namely for Kirby and Smash). So don't expect Sakurai to do a standard Nintendo franchise game. This game will be a new IP that Iwata said that Nintendo couldn't do by themselves.
Again this is not a new entry to existing Nintendo franchises. This is a completely new, never before seen entry that could give rise to a new franchise if successful.
