Ok, I´ve got some time to kill (which has rarely happened these past months) and I want to participate with the fun
If Canon is to release 7-9 lenses next year, I´d take a guess:
1. a big surprise lenses nobody thought was possible: a 90-180mm 1:1 macro zoom lens.
2. RF-s 18-55mm F2.8 Z
3. RF-s 55-180mm F2.8 Z
--> or maybe a RF-S 9-20mm F2.8 Z
--> I believe Canon will launch two RF-S Z lenses at the same time
4. RF 85mm F1.4 VCM
5. RF 12-24mm F2.8 Z
6. RF 14mm F1.8 L
7. RF 28-70mm F2 mkii around 1 kg
8. RF 70-150mm F2
9. RF´s 22mm F2 carried over from the EOS M system
Lenses 7 & 8 will be released together.
Cameras:
1. Retro cameras FF
2. R7mkii --> mini R6, designed like R5/6 and with a BG!
3. R10mkii --> current R7 internals, including IBIS
4. Vlogging based APS-C camera
I don´t know what kind of camera a RF-s Z lenses would be best suited for. Maybe it needs a new mode?
Obviously, R6mkiii is coming but that is not a prediction.
2026:
1. R8 mkii moving a little bit more upmarket: still no IBIS, but a joystick (a man can dream!) few tweaks here and there, coming Q2
2. R9 with no EVF and compact design (not really high hopes here) coming in Q4
As said, just guessing here
