Sure!
Is it the beginning of the end, but when will that end arrive? We still have people doing VB6 apps running on Windows XP. Somehow I have problem seeing a mass exodus to Windows 8 and javascript programming.
While the consumer side might be under heavy attack from mobile phones, apps and tablets Windows is still deeply entrenched in the enterprise side of things and they aren't exactly an agile bunch.
That the desktop application as we know it is already dying, on all platforms, but I will go faster in the consumer market then the enterprise and I think we can safely assume that both windows forms and wpf applications will still be around in five years.
