Ok, hold the damn phone. Are we seriously suggesting that all 5 of the stages are from new and existing franchises, that also don't have a character? Like, I could see 1 maybe but 5? I highly doubt that. I can't really see Inceneroar getting a stage either. Geno? Maybe we could talk about that but it seems like everyone who believes in the Box Theaory believes that the last two are Ken and Inceneroar
Take into consideration that there has only been what, 8(?) stages like that in ALL of Smash. Less so if Smashville and the Mii stages aren't included. What games do we expect to get a stage treatment but not a character treatment? I could see maybe Rythm Heaven but even then there's characters from there that I consider likely. Could they be from already represented franchises? Sure, but why would they wait so long to show it if they aren't also getting a character? I just don't see a game getting a stage without also getting a character. Maybe Nintendoland? But, again why not already show it?
Believe me I understand that the CoroCoro "leak" doesn't necessarily contradict the box theory but I personally fell like believing both is foolish. Because, basing off what we've already gotten, they wouldn't have hesitated to show off a stage that wasn't going to get a character. At most I feel like they could show a stage that would eventually get a character a la Boxing Stage and Little Mac but that doesn't see anymore likely. Sure, they don't contradict each other but there's no logic to them holding back stages unless it's for new characters. It doesn't make any logical sense.
