Any gamers worth their salt could tell you that StarCraft II will be big. As one of the most anticipated games in recent history, Blizzard's pending launch of SC2 is expected to bring in an insane amount of sales, so much that Activision Blizzard's stock has stumbled this month after rumors surfaced of a possible delay until 2010.

Meanwhile, one analyst is predicting that at least four million individual copies will make their way into gamers hands within the first few months of its release, whenever that happens of course. Basing his figure on the success of the original World of Warcraft beta and the popularity of the StarCraft franchise, four million in the short term seems plausible.

The original StarCraft has sold over 11 million copies in the eleven years it has been available. Yet unsurprisingly World of Warcraft still holds the crown as Blizzard's best seller by far with 11.5 million current subscribers, no small feat for a game that was originally released in late 2004 and has received two very successful expansion packs.
