A patent for the Canon EF 600mm f/4 DO IS has finally appeared. A prototype of this lens was shown in September of 2015 at the Canon EXPO. We were also told a few months ago that the retail version of this lens could be coming near the end of 2017, though we haven't received confirmation.
Patent publication number 2016-200685 (Google Translated)

We hope to hear confirmation of a release date in the coming months. We'd also like to see a price tag, but that's far less likely this far out from an announcement.
