2020 will be a busy year for Canon. The replacement to the EOS-1D X Mark II, Canon's top-of-the-line DSLR camera, the Mark III model will be announced around Q1, 2020. The high megapixel EOS-R mirrorless camera will also be announced in early 2020.
In addition, the EOS-R Mark II and EOS-5D Mark V cameras will mostly probably come on the market by late 2020 or early 2021. There are no information to these two cameras right now. Please check back periodically for the latest information.
