Canon EOR R and Nikon Z are both heavily discounted at the moment.

Regarding the current sales, pretty much all manufacturers are in panic mode I reckon.

I wouldn't say they are panicking, but they are in a fight to secure as many early adopters as possible. This is the start of a new-ish market, and someone spending $1-2.5k on a lens is much more likely to stick to a brand than to switch to their competitor.

Also, "on sale" vs "full-price" creates a very different psychological response in a potential buyer.
