Don't get me wrong, anything that the people responsible for developing and producing the K-3iii can use to demonstrate the viability of the Pentax brand to Ricoh management is good. But there isn't any competition from other new camera model launches at the moment, so a new model from a company with
~3% of the Japanese DSLR market gets to be #1 for a while. The fact that preorders are sold out is even better news, it means that actual sales have exceeded the forecast that was able to get the product launch approved, which means that the future of the Pentax brand is brighter than it was at the beginning of the year.
