In addition to the glowing colored lights, the body will be available in "fabric" colors like cotton beige, linen brown denim blue, tweed gray as well as "night sky" options such as sunset orange, dusk gold, moon silver, dawn purple and midnight black (green and black).
In addition to lighting up the controls, Pentax puts the mode dial on the back, where you operate it with your left thumb. The company did this so that it's more like a phone, with all the controls on a single plane. Also, look at how large that viewfinder eyecup is.
Moving the mode dial from the top to the back allows for a much narrower camera. The only controls left on top are the exposure compensation button, ajdustment dial and Pentax's hypermanual green button.
