Doesn't Xamarin have a load of other stuff around testing and the like?
It could just mean a move away from Xamarin as a core development tool into producing things which support development on these platforms.

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.
