My thoughts, here we go...
35 Character roster: It's alright, I would've liked more as I'm sure many would have, but look at all the extras we have. I'm sure the options and stuff will make up for the "underwhelming" amount of characters.
Clones: Yeah, it's true, I use a clone for melee, and I'm actually glad Falco's back, but I'm hoping he still has those few things that make him different than Fox, which I'm sure he will.
Ganondorf: Oh my, Ganondorf, you look so great, but there's a big chance you're once again a clone. This is actually my biggest letdown. I really wanted Ganondorf to have a fresh moveset, but as of now, my hopes are being flushed away.
Wolf: I know many of you hate the idea of Wolf being in instead of Krystal, and I agree, Krystal would probably be the better choice. But I am much happier with Wolf. Yes. I said it. Wolf is probably my favorite Starfox character, so I'm happy

This only applies if the prophets were indeed true and all the clues pointing at Wolf also prove to be true. And he better not be a clone...
ROB: ROB. ROB... Not much to say about ROB. Many are disappointed, as am I, but I'm sure like Melee, the people who didn't know and completely refused to like Game and Watch from the beginning will grow to like this Robot. But I personally would have rathered Geno, Isaac, or Ridley, but yeah...
Overall: I'm still anticipating Brawl, even MORE now, especially with the new videos of Subspace and the like. The roster may be a bit lacking, but that's what was said about Melee as well, so I believe this roster will be loved when everyone gets the game, chooses their favorite characters, plays for some days straight, and gets owned online by me.
