So we all know console minecrafts legs are epic, with combined sales of ~110k per week. But from the statistics page on Minecraft.net
they show sales in the last 24 hours. They're at 14k per day. Which means that per week minecraft for pc sells ~100k per week. So that's 210k. Per week. And we still haven't factured in mobile. Even though I have no idea of mobile MC sales, I think it's safe to assume 40k per week, which means Minecrafts baseline is 250k per week, or 1,05 million a month, or 12,6 million a year. And that's without christmas boost and boost from releasing on next-gen.
When will it pass Wii Sports do you think (Minecraft is currently at 54 million total).
At this pace, in about three years.
