Yes, there was some work at the recent Need for Speed sprint. Python 2.5 has
a PCBuild8 directory (for VS 2005) with a specific project for PGO.

Yes, they are.

I think Martin decided to keep VC71 (Visual Studio .NET 2003) for another
release cycle. Given the impressive results of VC8 with PGO, and the fact
that Visual Studio Express 2005 is free forever, I would hope as well for
the decision to be reconsidered.
