According to other top titles, I'm assuming sales to reach million copies soon, if isn't already. Dayz make 2.1 m after 4 weeks of top selling title. Good news, rangers and hamsters rejoice everywhere!
Last I heard D:OS had already sold 250K copies. Well deserved!
Hopefully they sell at least one million copies, just imagine what kind of game Larian could develop with a very large budget.
