Yesterday Blizzard announced proudly that over 1.5 million copies of the long awaited sci-fi RTS game StarCraft II had been sold in just the first 48 hours after the game went on sale last week. We emailed Blizzard's PR rep to get more info about those sales figures and got a little more info on the numbers.

The PR rep confirmed that the sales numbers reported on Tuesday included both boxed retail copies and digital download versions of the game. The PR rep would not comment on how many boxed copies were sold vs digital download versions "for competitive reasons." The rep would also not confirm how many copies of the game were sold here in the US and in other regions of the world for similar reasons.

The PR did tell us that in South Korea and in Taiwan StarCraft II is available but only in a free open beta version. It's likely that sales numbers for the game will jump when StarCraft II come out of the open beta period in those nations, particularly in South Korea where the original StarCraft is a hugely popular professional sport.
