This year Nikon did quite a revolutionary refresh of its DSLR line with the release of the flagship camera D4 and the high-megapixel cameras D800 and D800E, leaving some professionals with the dilemma to choose between the two of them.
But it seems that they are not done yet. Nikon Rumors reports that within a few weeks the new D5200 will be announced. This camera will replace the D5100 as a mid-range DSLR for consumers and enthusiasts.
In case its getting a bit confusing with all the different cameras, here a chart with the Nikon DSLRs for a better orientation. (via PetaPixel).
Will this be the last announcement of a new camera for a while? Sometimes big companies breath in for a few years and then breath out also for a few years, meaning it takes a while to develop new products and then release them in a big wave.
