He's my most wanted potential newcomer, but he isn't going to get as much hype if he gets revealed as K. Rool or Mewtwo. K. Rool is just quite frankly from a far bigger franchise and a far bigger gaming figure, whereas Mewtwo is... well... gigantic. Not Sonic gigantic but like the next level we've seen.
Again, if we get roughly 50 playable characters, that means we have roughly 33 that haven't been shown yet. If we don't get them until 2014, we're gonna get lazy bulk reveals. The same is true with stages, except we'll likely get far more of them (I'd say at least 55 stages total, or like 40-something stages left).
Oh, and we haven't even gotten a Pokéball Pokémon, AT character, Final Smash (sans Samus and WFT), trophy, sticker, game mode, online content, etc. confirmed.
Yep. They should wait to show us all that until 2014 instead of slowly rolling down the mountain at a faster speed like a good marketer. Yep.
