Canon announced only one Cinema camera in 2019, the Canon EOS C500 Mark II. Next year we might see two new Canon Cinema cameras.
One of these new Canon cameras will be the Canon EOS C300 Mark III (Super 35mm and 4K video), and it will have the same modular design as the EOS C500 Mark II.
The other one might be the replacement for the Canon EOS C100 Mark II. For this one it’s also suggested it may have the Canon RF mount (introduced with the EOS R system).
Finally, it seems 2020 will not be the year Canon is going to introduce 8K video to its Cinema line-up. We may see some sort of development announcement, though.
