Guys, its just a camera. one that hasn't even been proven to work or not work yet. Every manufacturer updates its FW at some point, Canon is no different and should be singled out for it .. In fact on dpreview someone told me that Fuji are the better company because they do regular FW updates with new features. I have no idea if thats true, but i dont see them getting bashed for.
For me there are different types of firmware updates. First, there a bug updates. The software is complicated and code may not work correctly, and not all bugs can be found before release. Hopefully that type of firmware update is fixed quickly once any problems come to light, which sometimes only come to light when many people start using the camera on many different ways.
Secondly, there are firmware updates that add extra features to cameras which were already selling well because a lot of people were already happy because the camera was advertised having features that people expected to work in a certain way. If the manufacturer adds features though, like Canon did with a large increase in features for the 7D mid life, and Nikon added a new focus mode to the D5, and Fuji, Olympus and Panasonic seem to add over the course of the products lifespan, then that enhances the product people already have, and is good customer service.
Thirdly there are the firmware updates that seem to add stuff that should have been working on release. The Canon eye detect AF for this R camera sounds like one of those imho. If you read that a camera had eye AF, you would expect it to work in a similar way to Sony. Maybe not quite as good because they have been refining that feature for many years, but to find out that it can't continuously eye AF, and that you can not use the a burst mode either, but will be able to in the future via an update sounds like it was not ready to be released. The software industry does that, they release a game for example, and as soon as you put the game in the machine it has to download an update before you can even play it, and will continuously receive updates. Sometimes they are fixing bugs, but also adding features which should have been on release, and also sometimes adding extra features. Hopefully it will not become widespread in the camera industry.
No doubt the fanboys will say 'I don't use eye AF!', 'I wouldn't use a burst mode when doing portraits!' That is not the point.
I have no doubt there will be updates to fix bugs, as with almost all cameras, but to add features which should have been there on release at some unspecified point in the future is not right imho. Yvmv.
