Just in case you did not see it yet. Revit 2011 (all flavors) have been released.
Second I just saw the posting on the subscription center that the Revit Extensions are available. They are very limited at this time, unless you are using Revit Structures (seems to be allot of Robot integration directly into Revit). Main one is the Shared Parameter Converter it provides the ability to change family parameters to Revit shared parameters. A second functionality is to add or replace shared parameters to one or multiple Revit families file in one process.
Finally several of the main stay tools are out for Revit 2011 products; Globe Link, Batch Print, Space Naming Utility, Autodesk Revit DB Link 2011, Worksharing Monitor and Autodesk Revit Model Review 2011.
