I hope so as well, the WinRT API is stripped bare. I was shocked to see how much of .NET's functionality they didn't port over to WinRT.
I'll agree that WinRT is not complete, but that's hardly COM's fault. The real story is that they thought they could replace decades of development platform evolution in a 3 year development cycle. And even in that 3 years, they didn't think things through very well, or make many attempts to learn from history. With that I would disagree that it's a good/bad, .NET/COM axis. Many programmers are productive with Win32 and COM in ways that they are not with WinRT.
