Starcraft 2: first month sales: over 3 million

[DirtyP2002]

I don't get this. Blizzard says 3 million in one month worldwide. Why shouldn't they include digital distribution?

Anyway, I actually expected bigger numbers. That is like Halo Reach first day sold through customers. I expected something like 5-6 million in one month easily.I mean it is Blizzard we are talking about. THE PC developer.
