With its high bit-rate 4:2:2 colour space MPEG compression, I bet the video quality will be miles ahead of any of the current MPEG4/H.264 compression codec used by most of the current DSLRs and ILDCs in the market. In view of the advancement of video codec in other larger sensor digital cameras of other brands, Pentax is just lagging thousands of years behind, leaving at the Stone Age! :-(
Bottom line: Will the next Pentax DSLR be equipped with a stereo microphone, at least?
