Both Nikon and Sony have a plethora of FF cameras, and one more odd sensor within the range only differentiates it a little, and adds a different purpose to one camera among many.
On the other hand, Ricoh Imaging did not make a single FF camera yet, and that one — if it ever comes — to sport a 12 MP specialised video sensor in it? Sounds like a suicidal choice.
Any sensible product manager from Ricoh Imaging would start with product specs that have a wider appeal and more versatile use. Currently 24MP and 36 MP sensors are used in prototypes.

Indeed. There seem to be more FF cameras on the market than ever before.
(Current or new models only):

Nikon: D610, D800, D800E, Df, D4s;
Canon: 6D, 5D3, 1DC, 1Dx;
Sony: Alpha 7, Alpha 7r, Alpha 7s, Alpha 99, RX-1, also the NEXVG900
Leica: M Typ 240, M-E Typ 220, M-Monochrom

Maybe even a few I missed. Even Fuji is said to be doing a FF in 2015. Ricoh better get moving, otherwise probably Olympus or Panasonic will do a FF before Ricoh.

Related to this abundance of FF's in the market nowadays, perhaps, I had a rare 'I really need to get a FF' moment yesterday.

A 19 year old girl in my area who works at a local cafe, and who I see sometimes shooting live music gigs, upgraded her Nikon D5100 a few days ago to a D610. She only had her D5100 (her first ever camera) for about one year, and only ever used the kit lens etc. Now she is rocking full-frame, shooting high-ISO low-light without a care in the world, whilst I chug along in the dark with APS-C. Sigh.

Come on Ricoh, I need to compete better with teenage girls like her.

Pentax is said to be doing a FF since ages, and that predates the "Fuji is said to be doing a FF", and the "Olympus is said to be doing a FF", and the "Panasonic is said to be doing a FF". We can say they have a decisive head start!

Let's see what's their next major project after the 645 "Z".

I might skip the 12 MP. If I can't print larger, there's not a lot of point for me. Sure, in poor light there would still be an improvement but that's not enough for me.

Supposedly Ricoh is committed to the 24 megapixel sensor. I don't really buy that there would be a huge improvement in high iso shooting with a 12 megapixel sensor anyway, when comparing similar print/viewing sizes with larger megapixel sensors. On the other hand, if you have a decent number of megapixels, it truly does make your APS-C camera obsolete. There would never be any reason to carry a D800 and a K5, for instance.

The A7S is mainly geared towards the video crowd, from what I've seen. That's why the 12MP resolution makes sense.

Pentax is more interested in photography than video (obviously) so I don't expect the sensor to be less than 24MP. Having said that, I think 16MP is enough for 98% of people who buy a camera - including me. More MP just means bigger memory cards, more hard drive space etc etc. I don't print in several feet anyway, I print in inches (or poster sized) when I do print. My 7.2MP Sony from 2005 was good enough for printing awesome poster-sized photos of my wife and kids, that I still have hanging on my walls, so 16MP is more than enough.
My wedding (2006) was shot with a 8MP Canon pro camera (1D MkII, APS-H) and the pictures made an amazing wedding book.
And that is the main reason why the K-3 has zero appeal to me over a K-5 IIs or even other 16MP Pentaxes. 16MP is a LOT of pickels.

One thing is for sure, MP will increase further. The improvements in technology are mainly coming from the mobile phone market. More MP are better for improving demosaicing accuracy and correcting CA, tilt, distortion, deconvolution correction of focus errors and motion blur, resolution improvement, prevention of moire in AA-less systems, etc. It's a more accurate sampling of the actual lens output, even if the sensel pitch is smaller than the diffraction limit.

The increase in MP/shrinking of sensel size creates big problems in colour crosstalk, individual sensel noise and DR/FWC, camera processing power, storage capacity, R/W speed and PC processing requirements. A lot of work is going on in this area:

2013 IISW Papers

I think temporal oversampling (up to thousands of exposures per shot) and perhaps spatial oversampling (the combination of nearby very small sensels) will eventually become commonplace. See this paper for an interesting glimpse into the future:

Ultimately the goal will be a sensor with 1-photon sensel (i.e. a photon-counter) in a 1000MP+ sensor, the QIS:
