Yep, my miscounting - I thought we were on 7.4 million last time round and that the 400,000 plus would take us below 7 million which is what I expect. Either way, it's crappy counting on my part so thanks for the correction.
But while I agree that we're looking at a less significant subscription drop than the previous "big" ones, I still think there's going to be a hit this time. The BlizzCon hype just isn't what it was anymore, and the entire presentation was a bit... Tired. The players have picked up on that, and I get the impression there's very little of the "OMGCANTWAIT" for Draenor that previous expansions has seen.
Just a thought.
All that said, you're right. May is going to be the one that hurts because there'll be no cushion for it, and I also think Q3 is going to see subscriptions take an absolute hammering thanks to the release of other games and the needlessly long wait for the new expansion. Honestly, I believe we're looking at the 4 million mark before this year is out... And maybe even lower.
Time will tell.
