The Mamiya DL28 it's again online... Let's see what PhaseOne does...but, remember that the P30 it's a 31megapixels but It has microlenses!! The Aptus-II 6 doesn't have microlenses, so good point for the use in the view camera at a very affordable price! Hasselblad-31, PhaseOne P30 and Sinar HY6-s65r have all microlenses...
