We'll probably go to the void/13th shard, led by Zenos's voidsent that Yoshi P heavily hinted at and we haven't killed. I bet the void and dynamis are connected because almost every single blasphemy has the same model as a voidsent. I wouldn't be surprised if Zenos's voidsent kept him alive, or at least his body, and it will play a role in starting the new Void arc. Since Zenos can't actually die through natural means, I'm sure he'll play an interesting role too. There are void rifts in the sky in Ultima Thule, so...
Or we go to Meracydia and the void story starts there.
