I updated my win 8 release preview with the $40 price. And i have read online that pirated versions can also be upgraded. Maybe this is a mistake Microsoft means to make. People who pirate mostly aren't going to pay anyways, this way they at least get some money and get to convert non genuine users to genuine ones. A win-win for everyone.
