The artificial inflation of the "here have the game for alost nothing, as long as you pay us a month" just ebbed away within a quarter. Well kinda. In reality it will be a superposition of bored players unsubbing and some returners not staying for long. These are essentially the numbers after they released one of the best raids in a long time and massivly pushed for previous players to return. Unless they have some major marketing ploy for the next 3 months, its a downward trend which will probabably increase over the next couple of months until it changes shortly before WoD's release, turns around and spikes again at launch. I doubt that they will get back all of the lost subs though.
