I'm not quite sure where I say that, I feel misinterpreted
Maybe I am misunderstanding, but earlier you said that:
In WPF the XAML was about users creating their own differentiated and customized XAML, but in Windows 8, they have done a lot of the hard work for you, adding a boatload of animations, effects, and styles that you can use. This - effectively - removes the need for designers in 80% of application developers use cases, and since blend is written in WPF, that now is also no longer supported.
So I assumed you meant there is no need to the Expression suite outside of WPF, which, I tend to agree with you, will probably not be promoted as much as WinRT in the future.
