OK,so what's this something special on the Pentax FF?

The reason they didn't run with it was cost - the cost of FF production was too high, the retail price too high, and their market share too small to support it.

I don't know that FF will be for the majority despite the enthusiasm here....... DSLRs have their place, and probably always will, but when "the majority" see just how big an FF DSLR is, Pentax or not, many will baulk at buying and carrying one over APSC, MFT, 1", etc. It isn't going to be the size of an ME super - it will be significantly bigger than a K5.

Eventually, I think the majority of buyers buying anything bigger than a phone or compact will go mirrorless. EVFs are getting better. On-sensor PDAF is getting fast. And size, or more accurately, IQ per camera size and weight, is the reason that mirror-less is on the march. The benefits of mirror-less (ie the savings in bulk and weight) increase with format size. I'm personally as excited by the possibility of a small WR, FF AF CSC with K mount (and a high grade built in EVF please) as a new DSLR.
