The choices for Bluray are interlaced or 24p or 1280x720P60. So if you shoot 1280x720P60 you can use that all the way through.

I still shoot interlace as all my stuff goes to SD DVD 60i anyway. I have compared video shot on my NX30 and CX700 in both interlace 60i and 60p directly over HDMI to my Sony 240Hz interpolating TV and I can't tell the difference because the TV interpolates things that are missing anyway !!! Even on my Panasonic plasma I really can't tell the difference both are 42". The big difference really comes when I want to take a still from the video. By choice I would shoot everything in 60P but only two of my camera I use for shoots can do that in 1080. ( the NX5U will shoot in 720P60 but the others can't. Easier to let the NX5U shoot 60i, XR500 60i and the CX700 and NX30 60p and I just edit on a 60i timeline.

When talking about the influence of Kell factor one has to look at where this may come into effect. Early sensors where close to or had less pixels than the displays but newer sensors have much higher pixel counts than the displays and the electronics decide what is to be recorded. The newer cameras are likely all progressive in image capture and only format the output for recording. Sensor pixel count for my NX30 , for instance, would be almost 3 times the display resolution. So even applying the Kell factor is still greater than the display resolution. Sony array also allows the electronics to identify off sensor detail in the interpolation. In these cameras the lens is really the limiting factor these days.
