The last few top laners were:
Yasuo (if you count him), Aatrox, Vi, Zac, and almost 2 years ago Elise.
I expect it'll be a Mage/something, hopefully with an escape, self heal or CC (I hate Nasus and Xin, please give me something to make them cry. Hard.).

I guess his spotlight will show him as a top laner, but with most champions and their spotlights they can be played on other lanes aswell. To be honest, I hope it won't be good as a jungler, but rather a top/mid Champ.
