A lot of what you are currently missing in WPF will come with .net Framework 3.5 "Servicing Release":

• Container Recycling for ItemsControl (as base class)
• DeferredScrolling (in TreeView)
  • don't know if I will ever use it
• DataGrid (new)
• Value formating without value converter
  • you know String.Format()?, use it in a declarative way<g>
• Effects
  • great looking HW interaction with shaders
• WriteableBitmap
  • writeable surface which is completly integrated in the WPF rendering pipeline
• DXInterop
  • Might become a killer feature. (At least team-mediaportal.com would have had some use for it)

Check out Rob Relyea's session "What is new in WPF 3.5 and Beyond" to get a feeling for all the new features coming. Bits are currently not available for download.

Quicknote: If you are a wpf custom control writer(1), check out the sources for the Silverlight 2.0b1 controls released with mix08 keynote: Silverlight 2.0b1 controls. It is actually a whole vs2008 solution, so you can even "learn" how to create tests against custom controls.

BTW: The new -and right now "Silverlight only"- DataGrid is also included.
