Hearthstone annoucements are the best, you first get some social media post saying they'll announce something, than you get the name of the expansion and if you are lucky, a card reveal, and a promisse of more reveals later.

Than, after 2 weeks of total radio silence, they start revealing cards one by one, and this teasing go for weeks until they eventual release of the expansion, just in time for the heat death of the universe.

And in the end, everybody will still play Pirate Warrior.
