We saw pretty much none in Brawl, but do you think we'll the series represented more in Super Smash Bros 4 instead?
I personally think we might. Because hey, I'm sure Sakurai heard the complaints about how the series was represented in the last game, and that he's willing to look beyond WarioWare for inspiration in this one.
I don't expect Wario's moveset to be changed
(Supposedly Sakurai said the reason Ganondorf didn't change in Brawl was to avoid upsetting player that mained him, and Mario moveset change in Brawl were reverted for SSB4 {I tihnk there ar other examples but he's the only one that come to mind atm}). but I hope the series doesn't get shafted as hard trophy and music-wise.
