Sorry, I don't get this "sad day" sentiment at all.
Pentax has not taken away any dedicated buttons for RAW shooters, they are
adding many dedicated one press buttons for the K-7! By the same token, WB button would be useless to you as well.
Just compare it with K20D - those 4 way navigation button only adjust focus points - and does NOTHING if you use single focus point. So as a RAW shooter, you have NOT LOST any functionality of single press buttons. Some of you may have use for the now separate ISO, WB, drive, flash etc; some may not. I mean there is a large part of the camera - image processing and JPEG algorithm that a RAW shooter would never use anyways; the same would apply to specific buttons and functions.
