What I really want to see is a collapsible high-end telephoto lens.  The long telephoto lenses are just impractically long; nobody's camera bag can hold a lens that's 18 inches long.  But most of the space is air, which means that the vast majority of space taken up by these lenses is wasted.  If Canon instead built their non-zoom telephoto lenses with multiple telescoping, locking segments, these lenses might actually be practical to carry around.

I think diffractive optics will solve that problem eventually. All of Canon's DO lenses are physically shorter than their non-DO counterparts. Sometimes significantly. Canon must have over a dozen patents related to grating and particle dispersion DO technology...only a matter of time before they have it perfected enough to use in a high end lens like the 800 or 600.

It will be interesting to see how Canon handle the Converter situation with the 800f/5.6.

Nikon are selling their 800f/5.6 with a dedicated 1.25x Converter, the other interesting thing with the Nikon 600 & I think the 800, is the Lens Hood comes in two pieces that fit inside each other, I noticed it recently on a trip where a Nikon user had the new 600f/4, seemed a sensible idea to me, at least it gives the opportunity to cut down the overall length of the Lens when in use if light onto the front element isn't an issue. With the Nikon 800f/5.6 retailing at US$18K, I imagine the Canon 800f/5.6 will be at least as expensive & with a built in 1.4x similar to the 200-400f/4 it will likely be a 20k Lens.

I bet neuro's already working out how to fit it into his finances...  :D

Not really.  I like having f/4 when I need it, and 840mm f/5.6 when there is sufficient light.  I'm actually leaving leaning the other way, toward the 300mm f/2.8 IS II.  ;)

I've got the 300mm f/2.8L IS II and the 600mm II and think the combo goes together well.  The decision on which to use is really tough when I need 600mm.  If I need to be mobile I go with the 300mm II + 2x III.  When I can go with a large tripod, I choose the 600 II. 

Now if only the 7D II would come out and make that 300mm f/2.8 II even more useful!

Kind regards,
Jason

Guaranteed it will breach the Nikon price. I have yet to see any Nikon or Canon equivalent lens price below the competition if it is newer.

So expect a 800mm IS II that surpases $18,000. I am thinking a nice round $20,000 at 3kg.
