Haven't we done this chat already?
What a K-02 needs, is the same thing the K-01 needs - Sensor Shift in video mode, 48kHz audio, minimum 50mbits data rate for h.264, prefer Mjpeg at 100mbits or Compressed Cinema DNG raw, and, most importantly, Turn The Damn HDMI on with Clean Feed 1080p 4:2:2 or 4:4:4 output so we can record using a Samurai or Shogun.
Of course, in a new body, we can get all that with decent ergonomics, but the K-01 could do most of it with decent Firmware.
Some say the Stills side of the firmware needs better AF, I'd agree at the telephoto end, but every modern Prime I've tried is close to instant.
