It won't be.
They just announced it so I'm giving it at least a year and a half, probably 2 years, sadly. *shakes fist at Blizzard*
Funny story, Back when I was playing WoW *shudder* I had a friend in my guild whose brother was a blizzard employee. At first I was skeptical of the leaked info he doled out, but after he predicted content 3 patches in advance, I was willing to believe him.
He told me that starcraft 2 is already a finished game. They finished it over a year ago, and they didn't want to compete with WoW while it was still in it's heyday. I think TBC kinda hosed the game, but whatever, it's still going strong and I don't care cause I quit.
I know this is third(fourth?)hand info and highly questionable, but knowing blizzard, I believe it, I mean, why would they want a couple hundred thousand of their monthly subscribers, and, like...all of korea, to stop paying them $10-15 a month for a game they've already MADE in exchange for a one-time purchase of $50 that they will then have to release expansion content for, but otherwise don't see a continuous return on the investment?
Grr...Blizzard makes me angry sometimes. Lost Vikings was their best/most original game, and that came out when I was like...nine.
