That's sorta my point, A FF Pentax DSLR is not going to be that much bigger than the current APS DSLR because APS is already using the same size lens mount, registration etc and those will not increase in size with a FF Pentax DSLR.
4/3 DSLRs are smaller than APS DSLRs are they not? Arent the lens mounts smaller, and the registrations shorter too? -- J.C.

We all have evidence that's not true in practice. The 4/3 system was designed from scratch, but a 4/3 based outfit is hardly smaller than a comparable APS-C outfit. For unknown reasons, cameras are as big as APS-C bodies (if not bigger) and lenses need one extra stop for getting comparable depth of field and IQ (as the smaller sensor needs approximately one-stop lower sensitivity value to be used for getting camparable noise). So a 150/2 on 4/3 is required for getting 200/4 performance on APS-C (which in turn can be comparable to 300/5.6 on FF). Or at least this is how I see things.
