Just a quick note:

The latest releases of Autodesk Products are just starting to ship and have become available for download if you have Subscription. So far I see that AutoCAD 2012, AutoCAD LT 2012 and AutoCAD Architecture 2012 are available for download on Subscription Center.  Expect to see more products (Revit, etc) over the next 3+ weeks.

Also you can get a sneak peak at some of the new program features by visiting the appropriate product page on www.Autodesk.com
