I see lots of wild price speculation...4,5 even 6K USD.
Fact is, especially with what's going on in the world, very few people can or will pay crazy dollars for this camera and it's attendant pricey RF glass anytime soon. Some can, some will, but most can't or won't.
Canon, like many businesses now, is in the hurt bag. They will want to sell these things and the RF lenses that are sitting around right now in as great as numbers as fast as they can. It will not make them any money at all sitting in warehouses.
So I think it will priced close to 5D level, or else all the wedding, graduation and other rank and file pros out there who actually make a living with these things will simply not be able to buy into the RF system any time soon.
Having said that, I am so glad to see they are making the camera so many of us have been waiting for.
As long as they keep it priced competitively and in line with what most users will pay, they will have a home run on their hands for sure.
