I saw in the Q thread that they had an event in Japan for users to test gear. A K-1 was there, so one of the people took a few comparison shots.

I'm really surprised how small a FF prototype made in 2000 looks next to the Q. Sure it wouldn't have been designed to have SR in it, but wow... Looks like a K-7/K-5 with a grip size wise, and anyone who has used that combo knows it's pretty darn close to perfect in handling.
