"The long awaited (is it soup yet?) Mamiya ZD appears to be ready to start shipping in Europe, following its introduction in Japan last December. It was shown by several dealers at the recent Focus show in the UK, and Calumet in the Netherlands now lists it.
MAC, the US distributor for Mamiya, is completely mum on the subject (could it be because they are also the distributor for Leaf digital backs in the US?) For this reason it may be that photographers in the US won't be seeing the ZD at all, or there might be a delay till the politics are sorted out."

FYI, in the year 2000 Creo and Mamiya formed a company called Leaf America.
