Well, I suppose people who routinely make and sell large high quality prints might find a use for 24 or (gasp) 36MP.
I realize that print making is a total waste of time given the unsurpassed experiences to be had by looking at all those great captures on your smart phone, but there are still a few deluded fools who attempt to practice photography as an art form that includes beautiful physical objects as a possible outcome.
If you look at the contemporary photography that is carried in most serious art galleries these days, you will find a lot of honking big prints.
My standard file sizes for medium format scans exceed 60MP, and I don't find that excessive at all.
Photography is a very diverse field. Like many other amateurs, the OP comes across as though he thinks his personal requirements ought to be the industry standard. Please remember that other people operate to different standards, and perhaps expand your vision by imagining why that is so.
Getting back to the original question. Would a Pentax full frame be a huge mistake? I don't know. It depends on the ownership's strategic intentions, on how much of an investment they intend to make or not make, and on how well they have conducted their market research and planning. I would be a bit surprised if any of us on this forum had full access to that information. (I like surprises, so if anyone wants to step up, feel free!)
I do think that if Ricoh intends to compete in the numbers wars that now drive equipment marketing, they will have to go a step or two beyond the K-3. The K-3 in itself looks like a very fine product, so I may well acquire one.
I also think that over the next few years the allure of increasing megapixels will begin to fade. In my view competition will shift to some extent from steadily increasing resolution to areas such as "features" and niche products.
However, I think the really smart players will move to building loyal enthusiast user bases via things like improved support and online/workshop based communities. For example, I would say that strong promotion using events such as sponsored workshops (as in the old Nikon School of Photography) could be valuable in educating, thereby attracting, new enthusiasts in areas with an emerging middle class. Or maybe smaller workshops where people are given loaners to get the feel of a product. By coincidence I was at a meeting this evening where an experienced marketer touched on the idea of "authenticity", which roughly means interacting with customers in a manner that recognizes their individuality and draws them in by educating interactively rather than simply broadcasting homogenized drivel. (I guess authenticity is something of a buzzword in marketing these days, but that doesn't mean it won't work under some circumstances.)
Anyhow, as the owner of a quite a few fine vintage lenses that won't work with K-Mount, I will probably also buy a Sony A7r- and that camera will likely be the platform for much of my serious work. I think the K-3 and A7r would complement one another nicely.
