It's nice that the battery grip has the "joystick". Also note the padlock symbol on previously unlabeled button that garnered so much speculation.
Earlier prototype (ignore the box and arrow although the body contour is unchanged):
Mr. Wakashiro gave a nutshell explanation of their design philosophy and goals:
"Starting with the PENTAX K-7, we have designed all APS-C flagships to be compact, durable and functional, while packaging top grade performance in a small body."
These are many of the reasons why PENTAX users choose and own PENTAX cameras. Another reason
is the price for image quality performance and features compared to other brands. In these areas you tend to get more for your money.
Unfortunately keeping within a design philosophy and end price tiers requires compromises. If Ricoh were to design a camera that has every single feature that people "want/need" it would so cumbersome and expensive no PENTAX aficionado would want to use it or afford to buy it or would constantly be in the design phase as more and more features are added.
