The Windows 8 Milestone 3 was leaked out of Redmond recently. A few people have been poking around in the .dlls and discovered some interesting nuggets of information.
I have tried to pull together into a single post http://davidburela.wordpress.com/2011/06/14/premature-cries-of-silverlight-wpf-skill-loss-windows-8-supports-all-programming-models But to summarise, it seems that Windows 8 will have a new programming model (Direct UI & Jupiter) which is *based on a hybrid of Silverlight & WPF*. The new UI can be created and invoked through your language of choice e.g. C++, C#/XAML, HTML + Javascript. There are even talks that you can use the Direct UI Xaml and Javascript together, similar to how Silverlight 1 acted in the browser. -David Burela
