Through a communication in the financial world (an interview with CitiGroup analysts), Hoya (the parent company of Pentax) revealed that Pentax would soon be presenting one or more mirrorless photo cameras. This is clearly a leak and not a rumor (communication of false information in such a financial context would be illegal and seriously frowned upon) but it is still short on technical details.
On top of this, it is now clear that it will be a new avatar of EVIL camera equiped with an APS-C sensor. So, we will wait a good image quality, maybe with a simpler operation than most DSLR cameras.
Pentax announcement planned before Photokina.
