Really? So much over-reaction to rumored specs. Are we going to have to endure the same months and months of endless whining that occurred when the 5DIII was released?
Whatever Canon releases will be comparably spec'd and comparably priced to the 600D. It won't be identical, but comparable enough to compete, which is what this is all about.
As for the rumored specs, people seem to be reading them in the worst possible light. They describe a camera that is weather-sealed, has some magnesium framework (like the 600D), a slightly better autofocus than the 5DII, a slightly better frame rate and the latest processor. It is introduced at a price that is about $600-$700 less than the 5DII was introduced at. Is that so horrible?
We know nothing about the sensor itself, which means we know nothing about the quality of the images. Would opinions change if the camera performs at high ISO somewhere between the 5DII and the 5DIII?
Reminds me of the complaints when the 60D came out. People wanted all the 7D features for $1,000. Now people want the 5DIII features at $2,000.
