With no confirmed release date for SC2 yet, I'm thinking 2011-2012 is realistic, but 2010 would be wonderful. They did state that they wish to perfect the game as much as they can before release though, and as with WoW (and D2/SC to a very minor extent), they will likely fine tune Warden (hack detection) well for it, and of course take a few years after release to get rid of all the bugs and glitches as well as balance the gameplay/characters, then add more stuff, and start fixing the problems caused by that (at least that is what they did with D2).
