I wonder why they keep using the number of licenses shipped and not the one of the units activated....
Besides 2,000,000 are what 3% of the market? Not so good.....
Anyway these are my forecasts: by 2012/2013 WP7 will be abandoned and MS will use W8 in every situation. And yes this is possible because the OS is modular; check the size of W7 kernel.
