The previous rumor about another Pentax announcement right after PMA was true. You probably also remember this leak on a retail website about a new Pentax W90 waterproof camera. That one was true as well:
The Pentax W90 will be the first camera with LED lights around the lens for close-up photography. According to the picture it should have HD video and 5x zoom (ok, I will not comment on the substance in the picture above - I think besides water proof and shock proof this cameras will also be s**t proof).
The second camera will be the Pentax X90 - a 26x super zoom camera with a 12.1MP sensor:
Expect those two cameras to be announced on February 24th (+/- 1 day in the US).
