(in Japanese)
The above is the official list of all the discontinued Pentax camera models at the Japanese Pentax homepage. The K-01 and Q aren't been there yet but this does not necessary mean that so they are still in production. And, in the list we can see the VS20, which is a product that has never really appeared in the streets before it is discontinued. Really sad and what a pity! :-(
