Yes, but because native applications are here to stay, so it would seem, developers are in for a world of pain: writing your software for multiple incompatible platforms. This has been going on since iOS/Android at least, but it won't get any better soon.
Well, at least Windows 8 embraces HTML5 as a platform. They also have a new set of "Windows Runtime" (WinRT, not to be confused with Windows RT) APIs, which are consistent across all languages you can use to develop applications for it. Even JavaScript.
