What does WPF not have already that needs to be added?

I usually end up using WinForms for my limited GUI needs (very limited, desktop only), and that's mostly a wrapper around Win32 APIs that haven't really changed in 15 years or more. Does that mean WinForms is dead?

Although from what i heard at Ignite, they are making some improvements for touch support for WPF, XAML debugging, rendering performance, etc. It had maybe five minutes during an hour-long session on the future of .NET that I went to.
