I disagree with one point made below. FF actually allows LOWER quality
lenses to be
used because the absolute lines/mm doesnt have to be as high for same
quality of
results. Yes with some really bad lenses the softness in the corners
may become more
visible, but with decent lenses, FF puts less emphisis on lens quality
than apsc does.....

P.J. is right, at least in my case. If/when Pentax introduces a full
frame DSLR, I will probably buy one (eventually) but I won't be one of
the first in line. A full frame sensor, by itself doesn't really gain
you anything except:
1) shallower DOF (at the same focal length, compared to a APS-C)
2) losing the crop factor (meaning your 15mm is a 15mm FOV instead of
a 22mm FOV) - helpful at the wide angle end and for tilt-shift lens
users.
3) more megapixels (potentially significant depending upon the pixel pitch)
4) if a larger pixel pitch, then potentially better noise performance
at equivalent ISOs
The downsides:
It depends upon what sort of shooting you do, but a larger filesize is
probably going to mean lower frames per second on burst performance
for action shooting, compared to a APS-C camera. Fewer frames until
your buffer is full and has to wait to take another shot.
Larger filesizes means more computing power to post-process and store
images (something we seem willing to live with).
Macro shooters will find thinner DOF to be a disadvantage, rather than
an advantage
Full frame DSLRs will really show the deficiencies in your lenses,
particularly in the corners.
That said, Pentax probably needs to produce a full frame DSLR, just to
show they belong with the "big boys" and prevent some (more) from
jumping ship to another brand.
For my part, I love wide angle but find that the Sigma EX 10-20mm more
than meets my needs on the wide angle end of the spectrum on a APS-C
camera. I also love macro, so the increased DOF is a plus on an APS-C.
The K-5/K-5 II already leads the pack at high ISO performance and the
megapixels already exceeds what I need for the print sizes I will
realistically ever print. I can get shallow DOF with my Sigma EX 28mm
f1.8, my CZJ 35mm f2.4, and my 85mm f1.5s (heck, the DOF is shallow
enough in many cases on my Bigma - why would I want to make it more
challenging?)
In short, the Pentax flagship cameras meet or exceed my expectations
right now and a full frame doesn't do a lot for me other than let me
proclaim that I have a full frame camera.

From: "J.C. O'Connell"
Seriously, what is the latest rumours about FF Pentax dslr?
The latest seems to be the "officially deemed FAKE" mid-March 2013 rumor
that Pentax would announce the K-3 using Sony's 24mp full-frame sensor.
Instead we got 9 bold new colors for the K-30 (which BTW was no longer
on display at Tiger Direct during my weekly music/computer store
pilgrimage last week).
Since then, all I'm aware of is the recurring generic rumor that Pentax
will announce a Full Frame DSLR "next year".
The beauty being that the the rumor will always be fresh, there is always
a
next year...
