TC = Full Frame Pentax is around the corner

With a 1.4X TC the image circle produced in the focal plane suing a DA lens should just about cover a 35 x 24 mm sensor.

That is a possible practical and logical reason for delay (let's leave childish Hoya conspiracy theories aside). The TC needed to be tested on FF DSLRs as well as on current Pentax line. Also secure the optimum image quality using all DA lenses on an FF body.

No? If I were the manufacturer, I would make sure I make a piece of optics I don't need to replace in 2 years from today, or issue another version and confuse the hell out of customers.

TC being ready means the FF DSLR is ready too.
