"Presently the XNA Game Studio is not in active development and DirectX is no longer evolving as a technology"
Sure, they later said it was a mistake, but there are too many weird tales about DirectX lately. I guess they plan to do something stupid with it indeed, continuing the streak. To be honest, I have no idea what that might be, giving that DirectX IS core technology, but on the other hand I would have never even imagined that someone would be crazy enough to bolt-on a unavoidable phone GUI onto a desktop OS. So you never know with MS now. Maybe they really want to replace it with OpenGL or something and keep DX in the system only for the "legacy" (on the crazy-scale, this move would be actually below their most actions of the last 18 months).
