Windows phone sales are down 73% from the same period last year. I can't see how this is sustainable or why Microsoft would continue to invest in a platform with no hope of a return.
It's pretty clear that Windows phone isn't going to ever achieve a meaningful market share so it's pretty obvious why no one wants to invest in making apps for the platform.
