I ran across these today on the Autodesk website Civil 3D product pages. These are the first of many new bits of information that are becoming available.
AutoCAD Civil 3D 2009 Product Brochure (6 pages)
AutoCAD Civil 3D 2009 Questions and Answers (13 pages)
AutoCAD Civil 3D 2009 New Features Workshop
Hey just found tons of 2009 documents (lots to read here e.g. Getting Started Guide, User Guide, Tutorials, and my personal favorite, Best Practices Guide, etc.).
I hope this will help those of you that have been curious.
