Are any pro's going to buy this before the end of the year due to not having any business?
I dont want to be to political, but here are my experiences and my opinion on that: At least in germany the business isnt that bad for professional photographers. Most companies are still running production and while the economy took a hit, its not like there is no need for commercial photo-work. product photos can be done in a studio just like before, so no problem there. Same for other commercial photorgaphy, brochures, flyers, architecture, etc.
Also by the middle of summer travel possibilities will be in europe completely back on track, so this is (in my opinion) another topic where the R5 could shine with the high resolution and small body
Event photography is certainly not happening right know, especialy weddings. But some smaller weddings are allready starting to happen. By september (when the R5 likely will arrive in germany) I can see quite some more weddings to happen. The next season will also be most likely be twice as packed, we allready get inquiries for next year. I think the R5 will absolutely shine for weddings: perfect resolution (high, but not to high to be bad in low light), a handy body, canon colors and probably good ergonomics, most awesome lenses, silent shutter(!)... all these will be great for wedding photographers
So overall the impact wasnt that devastating and by fall, when the R5 will be available in germany, I guess most photography businesses will be back to normal.
I will preorder a R5 as soon as possible. If it holds up my expectation I will sell my 5D IV, 1DX II, Sony A7R IV, Panasonic S1H, Gh5 and GH4 and replace these 6 cameras with just 3 R5 cameras
I expect it to replace all cameras equaly or even better in terms of photoquality AND videoquality
