I highly doubt Microsoft will release and support Linux/OSX/iOS/Android API bindings. What will likely happen is Microsoft will : * open source the core libs * open source the JIT * make sure it works on all platforms * open source the ASP.NET and port it to Linux/Mac so they can separate Azure from being a Windows only cloud service Xamarin then packages these in to Mono and Xamarin.iOS/Android providing a layer on top of MS core stuff. Microsoft will then be able to sell .NET as a truly cross-platform solution and make VS/Azure more popular where it's probably losing to other OSS ATM.
