Well, if they did it, it would make sense to size the sensor so it would
fit within the existing DA image circle.
Quote from one of the rumor articles:
"The concept is to finally shake the creative shackles of the 35mm
'full-frame' format legacy which is based around motion-picture film
format."
And ...
"The width is that of the current Pentax APS-C DX sensor, while the
height is that of a full-frame FX sensor."
"Because the image-circle of the square DFX format is no larger than
that of rectangular DA format, it could allow complete compatibility of
Pentax DFX bodies with DA lenses (and of course FA, A, M, K, S lenses).
The total DFX sensor area is 1.5x larger than APS-C. Based on the same
pixel-pitch as the K20D's sensor, the new DFX sensor in the K3D* should
field 22 megapixels (21.94MP)."
Anyway, it's an interesting idea, and I don't see where it would require
Pentax to abandon the DA lens line.
And instead of having to play catch up to Canon & Nikon. Change the
paradigm and make them play catch up to Pentax.

Then I doubt that it will happen, because it wouldn't support the sale
of any new lenses. Pentax isn't likely to abandon their investment in
the DA line quite yet.
