Here are some new rumors on Canon’s big megapixel DSLR. According to the source, the name would be Canon EOS-1D Xs or 1Ds X. And it is likely to be announced in Fall 2013.
This 1D Xs will mostly have a 47MP full frame sensor, also the 39MP and 50+MP versions are both in test. The camera is dependent on technologies that will appear later this year in the 7D Mark II. There won’t be availability until Q1, 2014 at the earliest.
