I think the fact that they demoed IE10 running well on a 1.0ghz ARM, coupled with last year's emphasis on Windows 8 running on an ARM device, speaks volumes about the future. Windows has had HTML/CSS/JavaScript "native" apps since Vista. If IE10 + Win8 results in "native HTML5" being performant even on mobile devices, it seems likely that HTML5 is soon to be the new Silverlight in terms of simple out-of-browser apps.
