Actually the 645D went into an open area of the market, an inexpensive digital MF and therefore there was an opening for the product with little or no competition. Nikon and Canon already had a huge professional base from the film days in which to plug the FF digital. For Pentax FF to compete the company needed to produce a large number of new lenses plus places to rent lenses etc whereas the 645D eases into an area where there is little choice at their price range. It is not a matter of if Pentax can make a camera but if they can make room in the market for them. And it is all beside the point as the K-01 is not made to replace FF nor was the Q. The 645D might have been and Pentax is most likely right in there was more room for them in MF than in FF especially with the slower AF they currently have.
But all that is beside the point, Pentax made this camera as they think there is a market for it. If the AF is much faster and better with the K-01 it makes sense that the larger volume of sales will more quickly make R&D back than the low volume FF. So why dump on this camera because it is totally different animal from what you personally want? It sounds like only FF will do for you and until they make you one they should not make any new models for the rest of us.
Not to rain on you too hard here: I think it is unlikely the AF will be better than the K-5. You cannot do phase-detect AF on a mirrorless camera, so it will have contrast detect AF. It can be really good contrast detect AF, but it is harder to do it that way. Pentax actually does have a huge volume of existing K-mount lenses - they would just have to make a mechanical "feeler" for the aperture pin to un-cripple the KAF2 mount. Nikon has figured out how to do it, Ricoh could too.
Personally, again, I think the 645D proves there is room in the market for a Pentax FF DSLR. Something at the $1500-$2000 level would sell like hotcakes, since the new Canon/Nikon FF bodies come out at $2500+. Even used 5Ds still command what, $900 or so these days? That's a used, nearly 2-generation old camera.
But I don't know who the Pentax Q was for (hipsters?), and they still brought it to market. I'm really not sure it'll last, but who knows. This seems to be a really awkward straddle of the DSLR and Mirrorless classes, pleasing no one. I think I would have been much happier if Pentax made a really good NEX clone that could autofocus K-mount lenses with an adapter NEX-style. It would have been thinner/smaller and eliminated a lot of my complaints (the other big one being the extremely long register distance for a mirrorless camera). I'm a lot less displeased with it now that I know they're not dumping legacy lenses a second time - dumping screw AF lenses would be too far in my book.
I don't honestly know that Ricoh is much better than Hoya was. Look at their GXR system - they make the most expensive part of the camera interchangeable. You can buy a Leica-M mount module that doesn't mechanically read the focus cam, so it's basically a wannabe mirrorless anyway, for the low low price of $650. Or you can buy a kit lens for only $579, what a bargain! Same problem - it seems like they don't really think things through before they develop a product.
