Yeah like others have said what exactly is the source of this poll. Would be pretty big news if it were true.
Though I think we were done with base game 3rd parties from companies not represented with Simon's announcement until DLC happens anyway. So regardless if this poll is real or fake. I've kinda felt this was the case though I would think the Ballot would already still signify to Nintendo what we'd like in 3rd parties and for the exception of Crash amongst what the OP mentioned all of those probably had some decent following on the ballot.
So far the guesses (Italics are unconfirmed but possible) seem to be this for already represented 3rd parties:
Konami: Snake, Simon, Richter (echo)
Sega: Sonic, Bayonetta, Shadow (echo) and/or Tails
Capcom: Mega Man, Ryu, Ken (echo)
Namco: Pac-Man, Heihachi and/or Lloyd
Square: Cloud, Geno
Note: I'm not saying this will happen. Just if there's more to come for any of these, it's just what seems to be guessed by the general community. I'm not even that sure Namco is getting anything more character wise then Pac-Man for example but thought I'd toss in Heihachi and Lloyd anyway
