I've just answered your question in the support ticket you have opened, but here is a link to the Roadmap again:
The official release in Q3 2008 is coming up and most controls are almost ready. There is still time to put a feature request in development or a bug to be fixed so let us know if you need our assistance.
You can also subscribe to our blogs feed
where we post about the new controls and features and also put some helpful tutorials. I hope this helps!
