at what point is too much? 36mp is hard to tame. I think many Pentaxians will meet the same struggles I did when I first picked up a D800 in which every slight hand movement or flaw in your shooting technique is amplified. I doubt share reduction will hide it all. Then there is the pain and suffering you will inflict on hard drives and your processor of your computer. Don't be asking and glamouring for 40+ mp if your not willing to give them a solid support net.
In my opinion, 80% of photographers (Pentaxians, Canonians, Nikonites, Sonites, etc) don't need more than 16mp. Look at the m4/3 and Fuji cameras, they seem to be very content with 16mp. Same with cameras like the D4s and 1Dx...
Keep in mind that RAW compression options are still, well, options. Sony's A7R mk2 delivers 42 MP files that are actually just ~40 MB, and they do it quite well with 99% of shooting conditions not showing any quality degradation. And for that 1% all they have to do is offer 14-bit lossless RAW and they're golden. That's what Nikon does, but folks are usually too snooty to dare trying their D800 in 12-bit compressed NEF. I've been doing it for years on all my Nikons and it works great, ~1 MB per MP; almost as compact as a super-fine JPG file!

Two models expensive/cheaper at launch (or nearby) has precedents in recent FF camera history:
Nikon D3 (expensive, 12MP), then 12 months later D700 (cheaper, 12MP); Nikon D800 (36MP, expensive), then 6 months later D600 (24MP, much cheaper); Sony A7r (36MP, expensive), and launched the same day Sony A7 (24MP, cheaper). It can happen, and it has some marketing advantages. Plus the hard work that goes into building the expensive body makes making the cheaper body much easier.
Again, I don't think this will be Pentax' philosophy. It's true that others have done this, knowing full well that they'd make more $$$ just by spending more $$$, but I don't think Pentax is big enough to just rattle off multiple bodies and "let us pick"... They probably know they have one shot at doing this right the first time, for as many buyers as possible, and they'll only get to make a 2nd FX if the 1st one is a huge hit.

16 MP is great for almost everything, indeed. I could go my entire wedding & portrait career with 16 MP probably, as long as I have sharp lenses. Heck, I built my career with 6 and 12 MP cameras!
Having said that, keep in mind that Pentax is also the company offering the 645 digital medium format system, an arena where sheer resolution is one of the main factors in buying. You wouldn't buy a 16 MP 645s, would you?
I think that Pentax knows they must "bridge the gap" with a full-frame 35mm digital sensor. If 1.5x crop is "good enough" at 16-24 MP, full-frame's main purpose is not just to offer better high ISO and more shallow DOF, but to chase the resolving power of MF as well.
Of course that's just my opinion.
What is NOT opinion, by the way, is the fact that megapixels are no longer "harming" a sensor's performance by a noteworthy amount. The 42 megapixel Sony A7R mk2 is proving this with it's ability to perform almost on par with the 12 megapixel A7S in low light. It requires full sensor readout to get there, (as opposed to pixel binning?) but it's possible with the right chips and software speed.
TLDR; don't worry about megapixels too much. Worry about the execution of the finer details, such as will they offer 12-bit lossy compression, or mRAW, or full sensor readout for high ISO video. And of course, will the sensor be BSI or not...
