A more interesting question imho is, who can become SOTY again?
If I look at the list since 2000 (which is a bit of a stretch of course), most skaters are past their prime.
The only real contenders for a repeat are Ishod, Suciu, Kyle, Tyshawn, Foy, Milton and Mason. (I don't see Grant, Leo and Wes putting out more than one full part and some tour footage, and you definitely need at least two full parts.)
I don't see Suciu, Foy, or Milton winning again, because their skating is a bit repetetive (Foy) or not many different spots. I don't see Kyle or Mason topping what they already put out but you never know.
I would be stoked too see Ishod winning again, he murders every spot. Tyshawn is not very likely but my wild card.
A different crew and filmer might fire him up to put out a crazy part pr two.
