It is and has been a cash cow since dirt. The best Canon could do was stick even more glass in the optical train in the form of a flip in/out built in TC and call it a new model...the 200-400 L. No new news on when it will actually ship but it was announced awhile back. To bad they didn't just update the old dog 100-400 and make it a 200-500 with updated IS FL elements and new coatings. But, nooooo they had to stop it at the same ole 400mm and add even more potential light loss.
The new 200-400 is not in any way a replacement or update for the 100-400mm. It is an entirely new/separate lens. What gave you the idea that it was going to be a replacement for the 100-400? Did Canon tell you they were discontinuing the 100-400mm when the newly proposed 200-400mm f4 becomes available???
Likewise, the fictional 200mm-500mm that you suggested wouldn't be a replacement for the 100-400 either. It would be an entirely new, separate model.
When Canon updates/replaces lenses, they do so with newer versions of the same focal lengths and apertures.
For example, when they replaced the 70-200 f2.8 IS, they did so with the 70-200mm f2.8 IS version 2.
When they replaced the 300mm f2.8 IS, they did so with the 300mm f2.8 IS version 2.
Sometimes there may be a very slight departure from this, such as (almost two decades ago) when they replaced the 500mmm f4.5 with a 500mm f4. But the way they've done it for a long, long time now is to simply improve the existing lens with technical & build improvements such as more effective IS, better coatings on some of the optical elements, and weight-reducing design modifications.
They don't just go discontinuing a lens, make a whole new lens that has different focal lengths and apertures, then tell us that this completely different new lens is a replacement for the old discontinued one.
"Your" and "you're" are different words with completely different meanings - please use the correct one.
"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "moot point", NOT "mute point".
