We're told by a few other people that Canon is working on a “foveon like” sensor for their next generation of full frame cameras. The goal is to have the new sensor tech in their next “prosumer” camera, so perhaps that means a new large megapixel camera with a smaller body than an EOS-1, or the EOS 5D Mark IV in 2015.
The replacement to the EOS 7D will have a new sensor not currently available in the Canon lineup, but we're told the camera is being specced more on features, especially for fast action and video than brand new EOS technology. By the sounds of things, the new sensor tech is best suited for the full frame segment.
More to come…
