I dunno, folks. I think some of you are over-thinking this. It's clear they want to know where general interest is with fans or they wouldn't ask. I'm pretty sure from that they can piece together what fans are interested in thereafter. Plus, who knows, maybe they'll do more specific polls here, Matty or elsewhere after this one to narrow down the characters. *shrugs*
For something like the He-Man and Skeletor variants, I think it's pretty clear why that was added when you consider all the 200x variants that exist, the two remaining variant sets from vintage MOTU, as well as the unreleased NA variants. That's a lot of He-Man and Skeletor variants.
I also don't think hardcore POP fans should fret much. As long as one or both of the POP options ranks high, they know the interest is there, especially if Filmation POP ranks high since it covers almost all the characters. My personal belief is if POP Filmation comes in high and the POP toys do not, I don't think anyone at Mattel is going to give fans characters like General Sunder or King Micah before they do the major players.
That being said... if you want Double Trouble, Starburst She-Ra, Scratchin' Sound Catra and Shower Power Catra, then I think you better vote for the POP toys!
