Of course AutoCAD will be their first unveiling with the other desktop verticals coming shortly after. Personally I'm excited to begin working with the much refined and well performing Civil 3D 2008 compared to its predecessor versions. I also look forward to the new features in store for us with Design Review 2008 which you can check out on Scott Sheppard's blog.
