Next Xpac announced today:

Before the announcement, I assumed I'd resub for a couple months to play through the new content, but now... I dunno. Seems like kind of a yawn. Just more of the same shit.
The Artifact weapon thing seemed pretty cool tbh, and I guess the PvP changes are long overdue. But Class Orders -- the evolution of garrisons -- don't seem very exciting. And even more surprising, the new Demon Hunter class is disappointing. Just another tank/melee class. 3 new classes since vanilla, and they've all been tank/melee.
Otherwise it's exactly the same as every other xpac... new level cap, new zones, boring story. There's no way this will revitalize the game. There will be a bump in subs for launch, and three months later they'll all be gone again.
