The HD Pentax-D FA * 85mm f/1.4 SDM AW lens announcement leaked online on a German website (now removed) - the official announcement should be coming soon. Here is the translated text:
The new, high-speed fixed focal length lens HD Pentax-D FA * 85mm F1.4 SDM AW from the particularly high-quality “Star series” has three “Super ED” glass elements with particularly low dispersion to effectively compensate chromatic aberration. An aspherical lens corrects spherical aberration, coma and field curvature. The lens owes a high focusing speed to the ultrasonic ring motor with Supersonic direct drive. The abbreviation “AW” in the type designation stands for “All Weather” and refers to the weatherproof construction with sealing against water and dust. The manufacturer specifies the dimensions as approximately 123.5 by 95 millimeters. The market launch is planned for 2020, a price is not yet known.
Update - HD PENTAX-D FA★ 85mm f/1.4 SDM AW lens officially “announced” (still under development, launch expected in late 2020):
