Canon isn't selling much of anything. Only a very small number of an already shrinking customer base would commit to a $3500 camera right now, in the midst of a global pandemic, job insecurity, etc. It's not about selling the 5DIV vs the R5. Their sales are probably down 50% or more, and as savings are used up around the world, luxuries like a new camera are not going to be on many minds. Of course, pros who need one and are still making money will get one, but that's a very small market. This is probably the time to hunker down, pause all R&D, reduce marketing, manufacturing and capital expenses and hoard cash, not release several blockbuster cameras. Maybe they feel they have nothing to lose with the R5, it's already done. But it makes total sense to delay the R6.
