According to latest rumors Canon may announce a new astrophotography Mirrorless in 2019. As far as I can remember the last Astrophotography DSLR camera from Canon was Canon 60Da and after that no Astrophotography camera announced from Canon.
Rumors suggest that next EOS R Mirrorless camera with a fullframe sensor will be dedicated to Astrophotography. A fair attempt to gain more user base for their Mirrorless divison.
The rumor is coming from anonymous sources of rumor mills, take with grain of salt.
