That spreadsheet you linked looks like some people voted multiple times to boost certain categories. I know the last time I saw it there were some pretty significant differences:
-PlayStation 3 was in last place, with Xbox 360 being in the lead by a fair amount. Kind of funny how PlayStation now just so happens to be tied for first.
-No female characters will keep me from buying this game DEFINITELY did not account for over a fourth of the votes; there's simply no way I can believe that number.
-The SpecOps pack had a lead, but it wasn't quite as massive as it is now.
-Security/Resistance was pretty even, about 52%/48%.
-Light/Medium/Heavy was around 45%/35%/20%.
-Class spread was pretty even, though I believe Operative and Soldier were leading slightly.
-Light weapons had a commanding lead; I seriously doubt that sidearms will be the most used weapon type. Another stat I simply cannot believe.
So yeah, I'd doubt the validity of that poll at this point.
