I know this is TECHNICALLY not the right thread to mention this, but seeing as it's been brought up now, and because I just want to put a quick word in:
Toad is not going to be a playable character. And I honestly don't get why so many people want him. He's a generic NPC, not a singular character. Yes, we've had playable Toads, but we've also had playable Shy Guys. And while Toad was playable in 3D World and the NSMB games, it's clearly just a case of "we needed a 4th character with a similar size and hitbox to Mario and Luigi" (Rayman's recent games do the EXACT same thing with Teensies). Heck, in 3D World's case, Toad's inclusion was completely unnecessary, since they could have made Rosalina playable from the get go if they wanted to. They announced her before the game was out, so making her unlockable was pretty redundant, as the surprise was ruined (even if you didn't watch the clip in the Direct, news websites and forums and what not did nothing to hide the fact she was in the game). The only thing justifying her unlockable status is the fact that she is objectively the best character in the game, even despite her slow speed.
I don't hate Toad or anything (in fact, SuperMariosChannel on Youtube has given me a hilarious headcanon for Blue Toad with their videos), but Toad's recognisable status has nothing to do with his actual character (he has none, especially since it's a SPECIES more than a character). We only know who Toad is because there are tons of them walking around in the Mario games. We can recognise Rosalina because she actually DID stuff (and because, for once, we had a character in the Mario platformers with backstory and who's personality wasn't just one dimensional "happy go lucky"). Toad, however, hasn't really DONE anything significant.
There's also the fact that it's been confirmed that Peach still pulls Toad out of...SOMEWHERE as her side B.
However, I'd love to see Captain Toad as an Assist Trophy.
