After the recent information (or rumour) that Sony is actually preparing a 14-million-pixel digital SLR camera under the name of either Alpha 200 or Alpha 300, and taking into acount that Nikon is in tight partnership with Sony since the Nikon D200, it is time to ask what resolution will come out of the next replacement of the D200.
I would bet on Nikon using the same 14MP+ for the Nikon D300 (as the D200 used a speedier version of the Alpha 100 10MP sensor). If this happens and the Canon 40D still has a 10MP or even a 12MP CMOS sensor, it could mean that the both Nikon and sony will have a nice time beating the Canon 40D just out of launch. Even if you repeat that resolution is not the solution to all problems, Canon would have to fight for image quality (and we know they are at the highest level of the competition) without having any resolution advantage, while users are still driven by mega-pixel figures.
