The funky K-01 has been getting a bit of attention lately. Everyone has been discounting them heavily (see Deep in the Discounts). Why? Because apparently Pentax is no longer making them and is unloading the remaining inventory. News out of Japan indicates that the K-01 is now at the end of its (short) life cycle, and it does not appear that there will be a direct followup.
Meanwhile, we've now got a firmware update (1.03, which fixes a focus bug while recording movies).
