Getting information on new firmware updates ahead of time has always been a very big challenge. I assume most firmware development has a soft release date because rushing firmware is never in the best interest of customers.
We're told that a major functionality firmware update for the Canon EOS R should arrive sometime in the first quarter of 2019. What makes the update “major” and what sort of features are going to be added were not disclosed. It was mentioned that user and media feedback is going to play a major role in future updates for the Canon EOS R and other EOS R bodies.
The source did say that it's possible a minor bugfix firmware update will precede the major release.
More to come…
