Compared to K mount (or m42) most other lens categories would be rare. But they supposedly sold 2 million coppies of the Auto 110, so there should be more than 2 million lenses around. Assuming that peoble buying an interchangeable lens camera buy at least 2 lenses, >4 million lenses is a reasonable guess. Risk is that people have been throwing them away, thinking them useless as the film format is basically dead, or that people simply lost them because the lenses are so small
Edit: If the Pentax designers have worked on a auto 110 compatible digital camera it may be economically madness in itself...but if the effect is that it forces them to make a truly pocketable camera, it may be the right design constrain to result in something that really would sell...they have to be different to stick out from the micro 4/3rd etc.
