>Do I understand from the road map that VFP/Sedna will have the correct look and feel for Windows Vista - "Windows Presentation Foundation (code named Avalon)" ?

That's one of the goals. As Craig said, MS has already shown some early Sedna ideas on WPF (Avalon) with VFP data. How to host WPF in a VFP form (if it is at all possible) or maybe just within a form in a ActiveX control or something is being studied AFAIK.

Ken showed VFP 9.0 in an early Beta of Vista and it looked fine. Getting to Avalon is a little harder.
