From the last one or two weeks, the impression I had was that it doesn't matter if WoW died... because Blizzard have alternative sources of income and is making a lot of money from them: Hearthstone, Heroes of the Storm, Diablo 3, Starcraft 2, Overwatch? oil? I mean I'm sure making the amount they did from WoW, they can afford to put that money into oil or other investment etc lol... so even if WoW become not profitable, the oil profit can continue to generate money for its development. It's just my hypothetical scenario.
If WoW just completely went to 0 sub or maybe stayed at 2-3 mil sub, can Blizzard still make a lot of money with these other franchises/method just mentioned?
