As I understand it, Visual Studio for Mac is simply a re-branded Xamarin Studio and will continue to be. It includes the improvements they had planned for the next release but I doubt they will do a rewrite.

I actually prefer Xamarin Studio over Visual Studio (on Windows) in some respects. For example, the Xamarin.Forms XAML previewer is much better. Looking forward to a full designer.

P.S. I've got a four part blog post series this week on Xamarin.Forms. Starting with this today: https://unop.uk/cross-platform-native-mobile-app-development...
