I mean this dude is basically saying the same thing I have ever since I've hopped back on SmashBoards:
The ballot was conducted
worldwide and open to
everyone.
Sure, Geno and some other characters may rank high on fan ballots from 4Chan, Gamefaqs, SmashBoards, etc. However, they're only targeting the hardcore speculation demographic not anyone else. So you're pulling from an arguably small portion of players and seeing their interest.
After all, most of these would have similar results due to it being the same demographic. Not to mention, a good majority of votes likely come from the same entrants.
So yeah, more obscure and unknown characters are likely to appear at the top given they're thrown around in speculation. However that doesn't equate to their actual popularity or fanbases.
So I wouldn't say it's completely wise to go off of what people are polling, for this iteration. It may give you some perspective for the respective demographic, but in no way is it representative of the majority of players.
