We are happy to announce that Archetonomy is releasing MegaDropDown for SharePoint 2010! We've been working on MDD for quite some time and are finally at a point where we're happy with the current feature set and performance.  There are two versions of MDD available:

• Standard - This is the basic version that can run on SharePoint Foundation Server 2010 and can create drop downs and manage basic navigation.
• Professional - The is the full version that allows you to integrate with Managed Metadata (Term Store), Managed Properties (Searching), and several other features that the full SharePoint Portal Server 2010 provides.

Over the next several days we will be posting updated datasheets and product comparisons. There are trial versions of the product available so please contact us at trial@archetonomy.com if you are interested.
