Let's see...Lorwyn, Alara, Zendikar, Mirrodin, Innistrad, Ravnica, Theros, Tarkir...Not exactly the best to derive a pattern from, but I do have a hunch the next block will involve a plane we've seen before.
More importantly, I think it's high time we revisited Karn and his quest to save those planes that haven't been devoured by the transfiguring oil of Phyrexia.
There is, in fact, one plane we know of, besides Dominaria (which already was the arena where Yawgmoth was obliterated) and Rath (now fused with Dominaria), that we've seen Karn on, and we've yet to revisit.
Thus do I suspect that the next set after Magic 2016 will be...(Noun) (Article) Mercadia.
(Unless we have reason to believe there's nothing more that can be done with the place, anyway.)
