If it was Blizzard, I'd be confident in a decent RTS. It's not Blizzard anymore. It's Activision/Blizzard, and screwing customers and employees is job #1 there.
BTW, Korea has rated SC2 at MA18 (or some equivalent). Which means all the little kiddies will absolutely have to play it.
But, that might limit sales, depending on laws there (I wouldn't know, but some countries are getting stricter on games than they due alcohol).
*edit* didn't see Dart's post*
While I have no use for the WoW grind, what criteria are you using? As an RPG, it is a unmitigated failure. It's not an RPG though, it's an MMOG. The RPG part is mostly ignored in marketing. Mr T, however, is not.
