If Asahiman is right and this is the name (and functionality) of the product, then it wouldn't make sense for Ricoh/Pentax to formally announce it before also formally announcing a "full frame" Pentax model. (Unless Pentax anticipates that there a lot of people looking to use theirs with their pZ-1p film cameras)
