I'm interested, actually more curious than interested, in how this turns out. I haven't experienced any problems in my photos. Given the way I use the camera, I'm guessing it's unlikely that I will.
>From my interpretation of the little actual information available, you need to use live view to get the sensor hot. It makes me wonder if they are testing with noise reduction on or off. Probably both, they do seem to be thorough. I agree with Bills comment on problem with mobile hot pixels, but I always thought that was common in long exposures. If not, why would you need to do a dark exposure subtraction after every long exposure. If the noise patter was always the same, couldn't you just run a standard NR routine? Just random thoughts. It's too bad. This is the kind of stuff that gets blown way out of proportion.
