What I still don't understand in this picture is the what does the future look like in terms of the .NET framework.

.NET Core sounds great, and its great that they are unifying the implementation, not just the API, for many of the "app models". But, its unclear to me if there's the intention for .NET Core to fully succeed .NET Framework at some point in the future. Or, rather, will some of the app models we see on top of the Framework right now (WinForms, WPF apps) be built with .NET Core in some future version?
