The market is definitely changing. Rebels will migrate to low cost full frame models or be lost to smartphone sales. Vloggers are a relatively new segment and they see smartphone not being able to (in the most part) fulfill their requirements so EF-M currently fits their needs but low cost full frame is an option especially for better isolation/depth of field.Dead cat bounce perhaps. The R5 and R6 were long awaited cameras. I'd say the glory days are over.
Canon will still sell alot of cameras but less and less every year.
Other than unreliability it will be hard to justify replacing them. The margin of improvement is getting thinner and thinner.
More intelligent auto focus perhaps, better battery life, its really hard to improve from now on.
IBIS might prove to be built in obsolescence and speed up the replacement cycle.
The path of improvement since my first digital camera in 2000 has been phenomenal.
I never thought they'd be so good at this point this quickly.
Even the lens have reached near perfection.
It just shows what humans can do when their brainpower is used in a positive manner.
I disagree that the margin of improvement is getting thinner. Yes, we have waited a long time between 5Div/5DRS and R5 but the improvement was massive - at least in the wide range of shooting genres I do. Well worth the bleeding edge cost 6 months ago. It wasn't as big an improvement compared to current Sony models though.
Everyone is now a photographer taking many more shots that before... mostly with phones. When they want shots that they can't do with phones, then there is a market for Canon products. What could be improved dramatically is the interface from camera to phone for upload or editing. Getting better but still not seamless even with the R5
There is a large base of 5Diii and 5Div users out there (and some 5Dii!) waiting for the right moment to start migrating. Second hand 5Diii and 5Div prices are still reasonable which is a testament to their build quality. Migration is an expensive exercise and will take time to completely replace EF with RF lenses... maybe even a decade but will still drive new sales as there are tangible benefits eg weight/size (RF70-200mm, RF100-500mm), eye-AF with RF50/85mm f1.2 for portraits, and innovation (600/800 f11). New lenses and cheaper RF mount bodies will also drive new sales.
IBIS and eye-AF dropping down to cheaper models makes a lot of difference to the keeper rates for users. If users can't get good or consistent shots, they will lose interest.
Battery life is tricky. There hasn't been a technology jump for a long time now for density (size/weight/capacity) with safety. Fab line width improvements are slowing as well so more clever system-on-chip may be the best option for camera life rather than assume Moore's Law continues indefinitely.
We just don't know how good cameras can get. Computational photography is yet to fully impact the segments we operate in. I was surprised by my iphone when switching to raw vs their default mode with how much Apple adds to their raw image.
Canon's announcement in a year where supply chain constraints, event cancellations, shooting opportunities in general and restricted movements is prety remarkable. Opening up of movements, events and easing of supply chain constraints will bring more revenue than 2020.
