The reason the Q matched the next size up is due to the 1/2.3" sensor being BSI, and no 1/1.7" were backlit at the time. The new 1/1.7" sensors are backlit, so Pentax will not have any significant advantage over the same sensors used in Olympus, Nikon, Sony, Canon or Samsung, at least not in raw images. The new X20 is one size up, but it is backlit as well.
