There has been a lot of chatter about the possibility of Canon announcing a high megapixel DSLR some time in October. I have a feeling most of this is rooted in the FM post from a little ago. We continue to receive emails stating the camera is coming and the camera isn't coming. So for now, I have nothing that shows an imminent announcement.
If something does come in October, I have a feeling it will be a development announcement or a camera that won't ship for a long while. There seems to be a growing concern that people are tired of waiting for Canon to release a high resolution camera. It's also suggested there's a growing number of Canon shooters that are buying Nikon and Sony cameras to meet their needs.
Our specifications for the EOS 7D Mark II came about three weeks prior to the launch, so if there is indeed a camera coming in October, there should be better information soon (Unless it's a development announcement).
