Oh, I know we're gonna see some more characters than those we have now. At least some unlockables, which we haven't seen yet (as far as I know).
I have two issues with Ridley;
1. I feel that he's simply too large to be in this game. And shrinking him to be the same size as the others would be so incredibly cheap imho.
2. His appearance and overall style blends very badly with the rest of the characters, and just feels out of place to me. But of course, this is also 100% subjective.
Also, I am so freaking psyched over the customization they mentioned. It's a shame it won't be available for online play, but I can understand why.
