I imagine it will focus on Hiccup's chiefing... perhaps showing that though he took on the mantle, he may not be ready for it. That is just a guess. I also know it will explain why dragons do not exist anymore, and I imagine that will have something to do with Toothless being Alpha (perhaps he leads all the dragons away). I will say that I think it is possible that Hiccup and Toothless will have to say goodbye forever. I also think we may see Hiccup and Astrid get married (at least that would be nice). Anyway, I hope Hiccup really faces some huge challenges as cheif, challenges that force him and Toothless to yet again make dramatic, self-sacrificing chocies. And I also feel (thankfully) sure that this next movie will be very Hiccup and Toothless oriented. The first two did a great job at that, and I bet the third one will as well. Anyway, this is all guess work... or at least most of it. We really don't have enough info for me to speculate further.

(I also think that Drago will return)
