Well, personally I am confused at how much vested interest people have over this.
Say it is true. Say the numbers are that bad or even worst. Great. The doomsayers were right. Then what? What do they get out of this apart a smug smile? Does it improve their life one bit?
As an active player, yes, I do have a passing interest but in the sense that I like see Blizzard continue active development in the game. Once that stops, I move on. There are other games and interest that can occupy my time.
But some people just have this obsession to see it fail. For what? Is it simply because the game is no longer fun for them and so they want to kill it? Kind of selfish attitude to have. And a rather unhealthy one. Possibly even unstable one. Now that is a scary though.
