@Dehnashi:At this point in time I think that Microsoft is still committed to enhancing WPF. WPF is, from what I can see, the way to go for desktop development. And that's important to the enterprise. When Windows Store apps overtake WPF than I'd say WPF's day has gone, but until then I think Microsoft will continue to enhance WPF.
Of course this is all my opinion; I've no inside knowledge of anything that Microsoft is or isn't doing.
