It is not a feeling, it is a fact. When digital came along, Pentax like everyone else had a fresh start in the competitive sales race. Sony for example, combining with Minolta, seized the opportunity and produced a FF in 2008, and came from nowhere to being Number 3. Canon of course had produced a FF DSLR in 2001, and Nikon in 2007. Pentax however waited agonisingly until the middle of the next decade before following suit, by which time any hope of becoming a mainsteam professional system had long gone.
While the professional market is tiny, the use of a system by professionals adds credibility to it and helps sales to serious amateurs. It seems that Pentax consequently now lacks that kudos, as in the thread on "Are we really THAT rare?" thread here.
I had given up hope of ever seeing a FF pentax DSLR, and one theory about Pentax's attitude I heard about 5 years ago was that if you wanted a bigger format than APS-C you should buy a 645.
