I asked, and my sources came through. I now know the announcement date for the Canon EOS R5, Canon EOS R6, and new RF mount lenses.
The big day? The official announcement will take place on or around July 9, 2020!

The image below seems to be missing a couple of lenses, most notably the RF 70-200mm f/4L IS USM and the RF 50mm f/1.8 (I think), so these probably won't ship until Q4 of 2020.
The same source has told us that the Canon EOS R6 body will ship in August, and that the Canon EOS R5 won't begin shipping until September. Ship dates have been a moving target thus far, but that falls in line with my original leaks that the EOS R6 would ship before the EOS R5.
Below is an image that shows the new Canon EOS R5, Canon EOS R6, and new RF mount lenses. Notice the new silver color on the RF 600mm and RF 800mm lenses.
