The interesting part is that Sony, Panasonic and Leica already made their official announcements for Photokina. Canon is still teasing their fans and Nikon is the only silent major player. Ok we still have Olympus, Pentax, Samsung, etc. but who is buying those cameras anyway (joke)? Are they really worth delaying a magazine for? Do they know something we don’t?
Last time when a German magazine was delayed was because of the D700.
