While it is a bit early I could easily see it doing 35 mil+ lifetime.
Honestly think the poll should have been shifted a bit higher since the game is likely to already be closing in on 17,5 mil in the next quarterly report juding by the sell-through number.
I thought the same thing about the poll after the first five votes had been casted. Adjusted "more than 35m" to a 35.1-40m range and added a tenth option to vote for 40m+.
As for the low end options, I don't discriminate against trolls.
