<Flame suit on>
ok i have problem with the marketing departments of all of the manufactures now, because of instead of improving the noise and compression algorithms, they have decided that competing in the my sensor has more pixels then yours is much better is much better.
the sad thing that most people dont get is that more pixels doesnt mean a better picture, only a bigger file size to eat up more card space, so on and so forth. plus most people dont even edit there images or store them and only take them to get 4x6's done or delete them.
i will bet a last nickel that all of these cameras coming out now with the 8 megapixel sensors will have the same noise issues as the sony 828, or other problems.
but anyways consumer cameras will never be able to compete with the DSLR's in sharpness and noise (or lack of) so it doesnt really matter to me.
my next camera will either be the Canon 10D replacement or the new 1D mk II
clive you are right: the med format back are a completely different league because the chips are twice the size of even the 1Ds and that the makers have even tighter QC in place so that the images are clean and crisp at higher iso's , but then again the price you pay for these is quite different and the same price as a car
FWIW
