Lost in all of the discussion of Win8's usability changes was the reality that Microsoft effectively deprecated ALL prior mainstream native Windows development paradigms and toolsets. Win32? WPF/.Net? Silverlight? Sorry ... nothing built with any of those paradigms will run on the new default UI of Windows. And according to everything being put out by Microsoft's marketing group, that isn't going to change going forward.
When I put this issue to our Microsoft account team, they said Microsoft "isn't deprecating anything" because the non-default desktop will still support traditional development for now. But saying the tools aren't deprecated doesn't make it true. If you can't build apps for the default UI that Win8 and future Windows users will see, then by definition the toolsets are dead men walking.
So IMHO, Microsoft orphaning all current Windows-native development methods is a far bigger story for corporate developers.
