I don't think that 14bit has to do with dynamic range. it affects colour depth. Dynamic range will be slightly different due to the option for iso80 on the K5. You will not likely notice the difference between 14bit and 12bit. I was talking to the people at pentax australia about this.
K30 = better video with the ability to shoot at 60fps @ 720p amongst other things, slightly better image clarity, slightly lower colour depth. Less ISO range. more battery options, improved AF
K5 = quiter, slighly faster burst rate, much larger battery capacity, slightly more colour depth, better build quality.
The fact is, most won't notice the difference. The will both excel at different things. I will have both soon, one for the video function and the the other for the battery life. Image quality is going to be an almost unnoticeable difference and i believe that they will make a killer team at weddings together!
