Well, if Sakurai does look at the poll, that's bad news for Rillaboom.
Cinderace - 6th (26,892)
Inteleon - 10th (20 697)
Rillaboom - 29th (8,625)
You could double Rillaboom's votes and it still wouldn't be enough to catch up with Inteleon, let alone Cinderace. Heck, you could triple the votes and Cinderace still wins.
This is part of the reason why I don't think Rillaboom would be a good choice. On top of it clearly being the most complicated of the three, I really don't like how many fans care more about slapping a grass type on the roster than they do getting a Pokemon that's both unique and a good choice to represent the Gen.
That's not to take a hit at anyone who genuinely wants it, because I know there are plenty of people out there who do. I just think those people are in the minority, being mixed in with a bunch of grass type supporters who already decided nine months ago that Grookey's evolution would get their support.
