Just a week ago, Sony announced that due to the semiconductor shortage, 
production of five camera systems had to be stopped in the meantime. And now Canon in Japan published a list of cameras and lenses via a press release, which have a delivery time of up to 6 months in the meantime due to supply bottlenecks.
The most prominent member of this list is the current mirrorless full-frame flagship camera Canon EOS R3. Those who order it today should actually not be able to hold it in their hands until the beginning of summer 2022 due to the tense supply chain situation. The Canon RF 14-35mm F4 L IS USM lens is affected by similarly severe delays.
The Canon Eos R3 is currently plagued by component bottlenecks.
And for the following units, Canon says you should currently expect more severe delivery delays as well:
Canon RF 16mm F2.8 STM Lens
Canon RF 100-400mm F5.6-8 IS USM Lens
Canon RF 400mm F2.8 L IS USM Lens
Eye cup ER-hE
Lens hood EW-65C
In fact, you can still find retailers that currently have the mentioned products in stock. In the worst case, the situation could even develop similarly to that of the graphics cards, if over the next few months only very sporadic models end up at the dealers, who then pass them on to corresponding interested parties above the RRP. But let's not paint the devil on the wall.
Now it is of course exciting to see how the delivery situation will develop for comparable competitor models from Nikon, Panasonic and Sony...
