With the 2020 Olympics being at home in Tokyo I assume Canon will be a major sponsor and will be looking to have new gear to impress.
The current 600mm is lighter than the previous version but its still a whopper.
It's like owning an aircraft carrier. It's expensive to build one but then you need to buy the planes to put on it and support ships.
The current 600mm is like that. You need a Gimbal Head and solid tripod and a good raincover and a suitable bag.
(The cases are great for storage but not for moving)
Smaller (more compact) and lighter would be an improvement. I can't imagine image quality being better but maybe its possible.
I'm sure Canon make some money from these lens but I assume they are more aspirational lens. Very few of Canon photographers will ever use them but they need to be recognised as the best and show up at World Cups and Olympics. Many Canon users dream of owning them and hope some day that dream will come through.

Another set of Supertelephotos has appeared in a Japanese patent application.</p>
<p>Japan Patent Application 2018-018101</p>
<ul>
<li>EF 300mm f/2.8L</li>
<li>EF 400mm f/2.8L</li>
<li>EF 500mm f/4.0L</li>
<li>EF 600mm f/4.0L</li>
<li>EF 800mm f/5.6L</li>
</ul>
<p>We’re expecting new supertelephoto lenses some time in the next 12-18 months.</p>

Is it possible the improvements correlate to new sensor technology that they will need to be even better? It seems that there are a lot of new patents for new sensors that I hope are considerably better and will that then require improvements in lenses?
