I've checked in the initial check-in of the upgrade project to the following location in the codeplex repository:
$/Branches/2.0 Upgrade
I have to admit that I am loving the fact that I can now use the integrated source control in the big boy version of VS. Since XNA 2.0 has handy new parameterized processors, I figure I'll just do my planned refactors to the pipeline in 2.0.
I don't have a binary release on this one yet, but stay tuned :-)
