Believe me, I want a 5Diii as much as anyone, but Canon is not going to release a new one until sales of the current one begin to slip below acceptable levels.
And that's not going to happen as long as there is nothing in it's price range that can match it's IQ.
We've gone from rumors of 3 new DSLRs in 2011 to none.
I'm starting to wonder what the true impact of that earthquake was on Canon/Nikon ...
And then there's Sony.
What if the earthquake pushed back the cameras far enough that they'd be post-Sony and thus not able to get a foot hold?
Or are (or were?) they waiting for the availability and price of components to be suitable?
There has been nothing substantial from neither Canon nor Nikon for too long. What's going on?
Is their next-gen sensor too hard to get right?
Also, if Canon can bring a 200-400+1.4x to market, that will create a substantial differentiator in lens offerings from what any other party can offer. If I was Canon, I'd have 110% effort on that lens, regardless of price.
