A new pro body
Suggestions of a new EOS-1 body to be announced in Q2 of 2014 have surfaced. No detailed specs have been given for the camera, which shouldn't be shocking this far out from an unveiling. Before the announcement, the EOS-1D X will receive a price drop and the new EOS-1 body would come at a $2000 premium. One would expect it to have a large megapixel sensor at least.
The camera wouldn't ship until well into 2014. Apparently this information is being passed around to select “pro” dealers.
A Q2 announcement would fall in line with the World Cup in Brazil as a testing ground.
