According to latest rumors on CR, Canon will release a new lower end/entry-level EOS R body in sometime 2019, and this new EOS R Body will not have the touch bar.
CR said this has been part of the entry-level EOS R plan for a while, and not because the user and media feedback about the touch bar has been mixed. Canon may also announce a new high-end EOS R body in 2019 with touch bar. And upcoming firmware update may correct some of the issues that some users have experienced with the EOS R’s touch bar.
