There is an update to the Revit Suite product line that will be available around mid-September. The update though is not to Revit, it's actually adding AutoCAD Architecture to the bundle! That's right, Revit Architecture Suite will now (well, soon anyway) include Revit Architecture, AutoCAD and AutoCAD Architecture. This was just shared with the Autodesk reseller community and more details will be available in the next couple weeks. Stay tuned!!
Again, I just want to re-iterate that this is NOT an update or service pack to ANY of the products listed...this point release is only being done to redo the Suite bundle for Architecture. The version of Revit Architecture that will be shipping with this Suite release is Web Update 1.
NOTE: This 2009.1 release will be English only for FY09.
