If there wasn't a WoW expansion coming up, I honestly think they would have skipped this year for blizzcon.
I'm not expecting much in the next few years either. Most of the blizz games I play I just don't expect big updates. Even for hearthstone, I knew a new expansion was coming just because it is just time for a new expansion. That is how card games work. They didn't need blizzcon to announce that.
