People said the exact same thing about pretty much every major release like when World of Warcraft came out. (And WoW took more players from CF than any other game will do ever, and its still only a few) Essentially its only a small handfull, perhaps just 2-3 people who are gonna play SC2 exclusivly for years, maybe even less. The MAJORITY is gonna play it alot for a few months perhaps a bit longer then grow bored/quit.
