What is Pentax waiting for??

I tend to agree with you.

Pentax has been on a mission since the K-7 thing and are very much it seems committed to the highest quality , low noise they can get out of a sensor. It seems that if a new sensor comes out and does not cut the mustard it is not going in a Pentax DSLR.

Since the production cost are so great, Pentax does not want to make a mistake, because with social media and this day of instant revue, your new camera could be dead in the water before it hits dealer shelves ..... something I'm very sure Pentax (and others) are very much aware of.
