Well, 6D is not gonna help any with the earnings once it is released. It is Canon's effort to pack the midrange with multiple bodies in the hopes that the buckshot approach covers that segment... all this results in lack luster bodies that don't necessarily stand out of the pack.
I think 6D will have steeper price drops than 5D3 within months following release. To expect otherwise given the high introductory price for this body is being overly optimistic. The added features may appeal to fanboys, but not to an average Joe who is not tied to the brand.
So expect Canon to turn out yet another poor financial report card in the next quater. The price drops in 5D3 are no coincidence...the demand is poorer than anticipated in the mass market. Canon still has one thing going for it....the lenses. But they can't ride that horse for ever. They will have to make bold moves. Bolder than 6D.
It is difficult for Canon to make a bold move with the 6D like it did with the 5DII, as it has to play nice with its more sophisticated bigger brother.
I can see the 7DII having the leg room to make a strong impression (although the current 7D still holds its weight) as Canon will not have as many concerns about it cannibalizing another camera in the lineup.
To make a splash the way the 5DII did, I would imagine the Canon video dept would have to drop a bomb of an announcement. The C300 & C100 are exciting to a degree, but the price point makes it hard to pine over. Given Black Magic's ambitious foray into the segment (with its many shortcomings), I believe Canon could make the biggest waves here.
Just my ¢¢ + a little wishful thinking.
