One with shorter register distance, smaller lenses and a new lens line, and one with the normal K-mount that will give us the ability to use the rich K-mount lens line. I am really interested to the second one. As for the first one I am O.K. with my $200 Lumix p&s.
I think it's doable in one mirror-less camera.
Let me go back to my idea of using the APS-C sensor inside that mirror-less, but not the whole imaging area of it.
Without a K adapter, mirror-less sports small lenses (in Auto110 style) for Kodak 110 film size image area (11 mm x 17 mm) projected onto the APS-C sensor (16 mm x 24 mm).
But with an adapter (retractable, as Dnas suggested) it can use the whole of the APS-C sensor area, same as Pentax DSLRs. It would be a terrific thing. DA40, DA21, DA70 .. get an all new life on a mirror-less *without* a crop factor. And in such a way both systems can share and not exclude each other.
It is roughly a Leica CL analogy, but not quite, because for ultimate compactness Pentax mirror-less would also have a small range of its own lenses and a zoom or two, which can be small because of the smaller imaging area such lenses project.
Neither Samsung or Sony can ever come close to such compact size of the lenses, because they still need to project image onto the full APS-C image size, and DA Limiteds already do that.
Thus Pentax can go down in size, and achieve same amazing picture quality as the DSLR because of the same sensor used.
When you think about this, one starts to wonder why Olympus and Panasonic ever started their 4/3 idea; they have ventured into the production of 4/3 sensors that can comfortably fit into the APS-C image area. Not only they wanted to reinvent the wheel, but are constantly behind others in sensor development game because they need dedicated sensors now and it means separate product cycles and money invested into the practically same thing, but with less resources.
Instead, they could think about a similar approach from day one and share the best sensors available with the rest of the industry, and within that tweak their own approach and philosophy.
