Here is another bit of interesting information.
Some of you may know the Japanese rumor website デジカメinfo (Digicam Info).
In a post dated 01/24/2016 "ペンタックスのフルサイズ機「K-1」は2月18日に発表?", a reader commented that a Japanese landscape
photographer Toshiki Nakanishi (中西敏貴) posted a photo with EXIF saying "PENTAX K-1 Ver.0.99". The picture was posted on Nakanishi's
blog on 1/29/2016, but, unfortunately, has been removed.
I guess it is perhaps not surprising that, as K-1's official release is coming, we may stumble across K-1's sample photos here and there on the net....
Original thread on digicam-info.com:

プロパティ内でプログラム名に”PENTAX K-1 Ver.0.99"とあるのを確認したのですが本物なのでしょうか?
