I took a drive to my most local Brick and Mortar Contax dealer (A place where I must admit that I've left more than a few dollars at over the years). These are long time Contax dealers and I thought that maybe they might have some additional info or insight. They had nothing that hasn't already been discussed on APUG except that it is becoming popular among Canon digital owners to buy the fast CZ lenses like the 80mm 1.4 and using them with adapters... whoopie.
