Avalon and VCL.NET future

MSDN again has interesting articles that detail what the forthcoming Avalon presentation system is. To me, it seems like a combination of Flash, OpenGL and ASP.NET/VCL style of declarative, XML based way of specifying your user interfaces and graphics.

For instance, these articles detail some of the features: article 1, article 2.

Now, there are posts on the Internet that Delphi's VCL classes would be easy to transfer into Avalon world, but I dare to doubt this.

Okay, for basic "business UIs" yes, but the more I study Avalon, the more I can find features in it that just cannot be supported by VCL.

It might be that I need to rewrite my WinForms UIs, but I wouldn't want to stick to VCL.NET either, for I'm afraid it won't last in the long run.

Mentally, I have no problem preparing to move straight to Avalon once it is here, but many Delphi people might be left out in the cold if Delphi will only have support to VCL.NET designers.
