Canon as well as Nikon make their new camera announcements in the weeks leading up to Photokina. So expect multiple announcements with the best coming about 1 week before.
As noted, Canon seems to have adopted a announce now - design later strategy. This prevents rumor sites from getting a good handle on a upcoming model for the simple reason that it does not exist.
About those announcments, what's happened to this page? No word prior to the 1d x firmware, nothing on the 6d, which has serious rumors elsewhere. Nothing stating Arthur Morris's founding that the 1d X focuses at f 8 with the Kenko converters. A lot of stuff going on, but The front page of this site have been pretty quiet for a while now. Seems firmware at least is an easier than lenses rumor to catch.
This could've been a fun topic for this site:
