5.6 million * $15/month = $84 million per month.
I'm pretty sure Blizzard isn't too worried.
Yeah, because the whole world is americans. The whole world pays in US dollars. And everywhere in the world people pay the same prices as they pay in the US.
Subscriptions is Asia work differently. People buy a bundle of hours. Say 20 hours for $5 or 40 hours for $9. (I'm making up the prices). A lot lower than prices in EU or NA. And those hours stay for many months. So you can buy 20 hours, and play 1-2 hours per week. Or play 1-2 hours per months. And you'll count as a full subscription. As long as 1) you paid for your hours, and 2) you played at least an hour or so during the 3 months of the quarter.
These Asian subscriptions make the numbers look way better than they are.
Reality: WoW soared to 5 million western subscription in November 2014. They had dropped to 2 million western subscriptions by March 2015. And now the numbers from June 2015 are probably somewhere around 1.5 million players left in NA and EU.
Prices for subscriptions in NA and EU are comparable. $15 or 13 euros per month. Less if you buy 3 or 6 months. So let's say $12 per month average. That means Blizzard's income on WoW subscriptions dropped from $60 million to $18 million.
Do you think Blizzard is still laughing ?
$18 Million is still a lot of money.
But I can guarantee you there are at least a few people at Activision who see it like this: "Blizzard lost $42 million per month on almost guaranteed income".
Subscriptions soared during the release of WoD. They went back to 5 million players in the west. Do you know what that actually means ? It means there are 5 million people, maybe more, who are dying to play WoW. To play that awesome game from 2005-2010, of which they have great memories. They want that. They are willing to try again. But 3.5 million of those 5 million said: "know what ? the game sucks. I'm done". I'm not sure Activision realizes it. But there is a huge potential for them to earn $500+ million *more* per year than they do now. All they needed to do is execute. But they can't.
It's like a heroin dealer standing in front of club full of junkies. Only the dealer forgot to bring the heroin.
So yeah, I think Blizzard is worried. Maybe not the cocky arrogant bastards that design the game these days (Chilton, Afrasiabi, Holinka, Hazzikostas, etc) . But I'm sure the financial people at the top (fuck Bobby Kotick, btw) are well aware what kind of money they are leaving on the table.
