Unless Pentax is totally daft, they won't abandon all the lenses they
just introduced. The DA lenses provide quite a bit more coverage than
is necessary for the sensor. Most of them work fairly well on full
frame. I'm sure the image circle will be adequate for IS. In fact they
probably have more overlap on a APS-C sensor than does an FA lens on a
full frame sensor.

Apart from superior image quality, reason good enough in my
opinion, a "full frame" FA D lens may be able to utilize in body
image stabilization. My guess is that IS won't work with DA lenses.
Why not?
Because the sensor is moving. It could then move outside the coverage
of the lens if the lens coverage is not larger than the sensor.
