If Phase works with Mamiya on this they would both increase market share if they keep the price @ the current offer of $10.000 USD.
PahseOne is not working with Mamiya for ZD.
In early 2008, PhaseOne will relase new MF body under PhaseOne brand. This will be improvised version of current Mamiya AFD II (already discussed in this forum). PhaseOne's Danish engineers are working on this body. Along with that, new lenses may be announced by Mamiya and other manufacturers.
In late 2008, PhaseOne will announce new higher resolution MDB.
