While sure, I'd buy Smash 5 regardless, cutting Diddy would be a major blow to the roster. And seeing as Smash 4 has mostly failed to attract the Melee base for a gigantic competitive scene (yes, its scene is pretty good, but it's playing second-fiddle to Melee for a reason), I'll probably hope for a more Melee-esque game from Smash 5.Seriously? The community would go in a riot if Diddy Kong got cut. It's bad enough that Donkey Kong got treated as badly as it did this game, imagine if it lost its second most important character. Along with cutting the nineteen other characters on the list and you're talking losing a significant amount of sales for the game. If Diddy Kong was cut I definitely would not buy Smash 6 (which I'm likely already not going to do considering Smash 3DS & Wii U mostly satisfies my need for Smash).
And why is everyone calling the next Smash game Smash 6?
