An interesting snippet from an article about cross platform efforts by Microsoft with middleware companies. Hurry Corona, I feel like we are last in line!!!

Make cross-platform technology easier and more capable
We’ve also been working for developers who may not already be on the Windows platform by supporting a mix of languages, runtimes, frameworks, and protocols that run across devices. Middleware partners like Unity have helped developers bring thousands of titles to the Windows Store. In a newly released beta version, Unity is delivering support for Windows Phone 8.1, including universal Windows apps.
Microsoft Open Technologies also works with various open source communities to contribute code to popular C++ frameworks and optimize them for Windows devices. For example, Windows Store supports Cocos2D-X, openFrameworks,OpenCV, Cinder, andOgre3D apps. Box2D and Bullet also have joined the Windows Store. jQuery now fully supports Windows Runtime, so web developers can build Windows 8 apps reusing their existing code and skills. Developers who use HTML5 to build cross-platform apps for iOS and Android with tools like Apache Cordova will find it easy to port their apps to Windows.
In fact, we’re taking a much more pragmatic approach to the web in general. We know that HTML is a critical cross-platform technology. Windows Phone 8.1 brings the same powerful hardware-accelerated IE11 HTML engine in Windows 8.1 to the phone. We’ve made great strides in extending IE to developers by focusing on open standards. Now we want to focus even more on interoperability. We already support WebGL and other technologies, such as media streaming extensions for adaptive streaming scenarios.
Today we’re also announcing that Microsoft Open Technologies has brought the Windows Library for JavaScript (WinJS) cross-platform apps and is open sourcing it under the Apache 2.0 license. Find the source code on GitHub. Use this powerful Windows development framework to build high-quality web apps across a variety of browsers and devices beyond Windows, including Chrome, Firefox, Android, and iOS.
