At the end of September the leading international trade fair "Photokina" for the photographic and imaging sector will be held. This fair is organized every other year in Cologne. All major brands are expected to come with exciting news about their product portfolio. The various so-called rumor blogs are already speculating on this news for weeks. It is expected e.g. that Canon will make announcements on their 1Ds mkIV and Nikon on a D90 replacement and a D3100. For more detail on the fair and all buzz around it I suggest that you investigate the links below.
