Olivier Bloch brings the good news:

MS Open Tech has been working with many open source technologies to help Web and C++ developers extend their reach and have their code work seamlessly on Windows devices.

You can now integrate your code using Cocos2DX, Cinder, Ogre3D, Box2D, Bullet, OpenCV, or Angle to a C++ Windows Store app project and rapidly get your app or game running on Windows 8 and published to the Windows Store.

And as a Web developer, you can benefit from the work done by the community and MS Open Tech to make jQuery fully support Windows Store apps, simultanesouly bringing other open source frameworks based on jQuery to the party, such as Backbone.js, Knockout.js, Canvas.js or Require.js. This means it’s straightforward for you to inject your JavaScript code from your web app to build Windows Store apps and offer a new type of experience to your customers.
