Wow, this is a popular thread! Six pages in a few hours. Looks like there's still some pent up demand for another long zoom from Canon.
Just to draw a comparison, the last zoom that Canon made that reached 600mm cost 880,000 Yen in 1982.

Lens design has moved on since, but sadly not the laws of physics. I still think that such a lens would be $10,000 plus and weigh over 4kg. With that amount of glass and mechanics, I don't think cheap plastic build quality would cut it. There wouldn't be much point in such a lens in the 'L' range, as they already have the superb 200-400 f/4 L IS USM Extender 1.4x.
More likely this would be a 200-500 f/5.6, like Nikon's. Personally, I think that it would be better for Canon to price this lens just above the 100-400 II and give it the 'L' treatment. The bottom of the market is already crowded, better to differentiate and go for a higher-end market than try to take on Sigma and Tamron at their own game. The Nikon version doesn't really show the third party lenses a clean pair of heels, as far as I've seen (which, to be fair, is only Internet reviews).
