Rumors floating around now
People are talking a lot about a 1D Mark IIIn/X. I've been told by someone at Canon that they will not be doing an “N” for the Mark III. Could we see a new 1D body altogether at Photokina? For marketing reasons, I really do feel an “n” version would be the wrong way to approach a replacement.
I'm still thinking you won't see a new 1D until PMA with the 50D.
