XBox is Metro-ish too, so you'll have to explain that. WP always has had an uphill battle, especially when you had phone salesmen trying to convince you you didn't want it (I personally ran into that at a Sprint store).
Microsoft is also developing WinRT (as an API) for a pretty good reason. WPF turned out too big and slow. I personally expect WinRT and WPF to merge later on down the line, and WinRT to come to the desktop.
Don't be so negative about everything.
