Canon will only make a 5DX if they don't mind upsetting a large portion of their customer base. Oh, wait. They already did that. New pro body which lowers the resolution (a tick against the landscape folk), reduces the crop size (a tick against the sports and wildlife folk) AND doesn't autofocus with f8 (a major tick against people using f4 superteles with the tc 2x, or the 800 5.6 with the 1.4x Anyone else feel Arthur Morris' rage?).
