I am told that the extension is now posted to Subscription Center. For more details about what is included in the Extension please see Ken's post from last week. Remember there are several software enhancements this year and it's not just an additional plugin.

• Six-month trial license of Autodesk^® Mudbox^™ 2009
  
  Designed by professional artists in the film, games, and design industries, Autodesk® Mudbox™ digital sculpting and texture painting software gives 3D modelers and texture artists the freedom to create without worrying about technical details. It can also be used by architects and designers in conjunction with 3ds Max Design to help create highly detailed organic architectural elements, such as capitals and other sculptural components or free-form terrains. Mudbox includes a highly intuitive user interface that makes modeling almost as simple as working with clay. It has a powerful creative toolset for helping design ultra-realistic high-poly 3D models, and a texture painting workflow that allows you to paint directly on your 3D models – vastly simplifying the process of painting detailed textures across multiple high-resolution maps.
   
• Autodesk^® ImageModeler^™ 2009
  
  This image-based modeling and photogrammetry software generates 3D models from photographs, enabling artists, visualization specialists, architects, and designers to view designs in the context of existing environments. In particular, Autodesk® ImageModeler® software helps you save time when working on renovations or projects in urban environments, where no documentation about existing buildings is available. Bridging the 2D and 3D worlds, Autodesk ImageModeler enables you to more easily capture reality as-built, take measurements of buildings, and create photorealistic 3D models and export them to 3ds Max Design, 3ds Max, or Maya in different formats (Autodesk® FBX® file format, OBJ, DWG).
   
• Autodesk^® MatchMover^™
  
  Considered a critical production tool at leading visual effects facilities, Autodesk® MatchMover™ software delivers high-quality 3D camera tracking. Using this toolset, artists, visualization specialists, architects and designers can extract accurate 3D camera and motion data from video and film sequences in order to insert computer graphics (CG) elements into a scene. MatchMover provides automatic tracking capabilities combined with the precision manual controls that professional artists and design visualization specialists demand.
  
  
• Connection Extension for Autodesk® 3ds Max® 2010
  

  The Connection Extension for Autodesk® 3ds Max® 2010 software makes it easier and more cost-effective to turn external designs into more accurate, creative advertisements by delivering new levels of interoperability, based on intelligent data workflows, between 3ds Max and design packages from Autodesk and certain third-parties.

  Features and Benefits

  • Streamlined compositing with OpenEXR -- Streamline your 3D-to-compositing workflow. A rewritten OpenEXR translator supports HDR workflows with advanced compositing applications.
  • Enhanced interoperability with Design Data – Bring solid models from many of your favorite CAD packages into 3ds Max for visual enhancement or conceptual design. A new high-fidelity SAT data translator helps make it easier to move solids-based data between 3ds Max and Autodesk® Inventor® Professional software, and certain other design products without translating to polygons.
  • Intelligent workflows – Helps save time with new, more effective workflows for dealing with complex scenes.
  • Extensive connectivity with Google™ SketchUp™ modeling software – A powerful new SKP file translator enables you to bring SketchUp scenes into 3ds Max with minimal effort and get right to work rendering or enhancing the visuals. Also, 3ds Max can now read numerous free models from the 3D Warehouse section of the Google website.
