When the Pentax Q was announced a year ago, the price for a kit with a lens was set at $800 which was pretty high considering the camera's specs. After the recent Pentax lens price increase, the price of the smallest mirrorless camera dropped by almost 40% to $499. The two lens kit now sells for $750.
Maybe Ricoh-Pentax will announce a new version during Photokina? Rumors about a new cheap mirrorless camera are already floating around.
