I don't want Dixie in, Donkey Butt don't deserve another character, especially a monkey, it would be fine if it was King K Rool, but I don't see that happening.
Besides we have enough females added, there's no point in adding Dixie, especially considering how ugly she is.
Same goes with that blue girl from Starfox, yuck.
I do find Shulk to be somewhat interesting, we'll have to see what happens with that.
As for Isaac, if he's not in, I'm throwing my Dark Dawn game out the window in rage, I might lose it, but who cares because if Isaac isn't playable in this game it could potentially cause me to somewhat hate Golden Sun and what it has become.
Ridley sounds like a good idea for a new character, I'm kind of hoping it turns out that he is playable this time, he'd be a awesome Newcomer, and Metroid deserves a new character instead of Starfox or Donkey Butt.
Mewtwo better return, Sakurai got us hyped for it and he did mention about not liking creating false hype and that's exactly what not having Mewtwo is.
Its bad enough Charizard is the only good Pokémon in and they have to add all those stupid Rattatas and that's exactly what Greninja, Jigglypuff, Pikachu, and Lucario are, they're Rattatas.
As for Earthbound, well I hate Ness, just keep Lucas, or better yet both, there are other stupid characters they could cut instead like ROB, Ice Climers, Game and Watch, Jigglypuff, Falco, and Snake, of course of all of those Snake is only one who actually isn't stupid, he will be missed too, but I just can't see four 3rd parties in this game.
Same goes for Wolf, he's a bad guy, which is better than some stupid bird, I hate birds in Nintendo games.
If there really is another Kid Icarus character, then please be Medusa, Dark Pit would be a stupid idea, e should just be a costume for Pit, and there's the fact he appeared with Palutena in that trailer at E3, well that doesn't mean he's going to be a new character or he'd be confirmed, hopefully he's just hinting that maybe Medusa is another character, after all we still haven't seen her appear in any form and you'd think she'd at least show up in some sort of cameo appearance.
Dark Pit should just be a costume for Pit, next thing you know Shadow Link will be put in, just no.
These dark ones should just be color swaps and costumes, like Dark Link, Dark Samus, Dark Pit, all should be costumes.
About Samus keep in mind like Waluigi in Brawl, she could still be a color swap/costume for Samus.
Maybe they're saving all these dark one costumes to be revealed when Medusa is revealed?
Btw I don't think we're getting dlc in these games, I don't think Sakurai wants to do it, he seems very reluctant about it.
