Compared to the 36MP of a D810, that's just a resolution advantage of 12.3% (linearly). There's more to MF than just resolution, but with a 0.8 crop factor compared to FF (D810, A7r, ...), the crop-MF 645Z is not a huge step up in quality but a huge step up in price.
The 645Z may be a bargain in the MF world, but compared to FF its market can't be that big.
Which exactly means that Pentax cannot rely on MF alone.
The price gap between the K-3 and 645Z is still too wide to swallow, and the linear resolution between the FF of other makers and the 645Z is negligible.
Which points, again, to an ancient saga:
the Pentax systems lineup does not make sense for its users. The lack of FF does not mean that 645 is the answer by Pentax to the FF question, because it is not. It is only a prolongation of the same agony. Because Pentax cannot build any
practical answer around the 645 lenses and its mount. Only impractical answers.
In addition, the FA and DFA lenses are wasted without an FF. Pentax needs the FF to fortify their own K-mount first, as anything that can be constructed around the 645 mount to "compete" with top FF boys is HUGE, and is not practical. And costs as twice as much at least. In a direct comparison, Nikon's D810 will win over the 645Z any time in people's minds, because it is more accessible, more practical, and
much cheaper. Disadvantages of the D810 are negligible when one puts it all down.
So I find it almost unbelievable that we are almost into 2015, and Pentax does not have an FF. Because many who want a 645, and can't get one, will opt for an FF of other brands.
The DSLR range in K-mount in incomplete without an FF, it does not make any sense. And Pentax loses its momentum every single Photokina.
