My long winded 2 cents below:
I think a lot of people are hung up on the word flagship and its skewed meaning for Canon. The R1 is a master of a field of content that has a global revenue of about a half a trillion dollars per year - sports. Now, the majority of professional sports photographers are making bottom to middle tier, middle class wages at most (between $30,000 to $100,000 per year - average top earners make less than $50k a year), so a lot of these people aren’t practically buying their own gear on those salaries and gear is provided by whatever company they work for. These people and mostly the companies they work for care about how fast and efficiently they can churn out quality content that’s mostly consumed and discarded in a short period of time. A lot of these photographers just care about a device that does what they need it to do and not much else, and I doubt you’d find many lounging around forums like this nitpicking about specs they’ll never utilize. All of this makes sense to Canon, the photographers, and the companies they work for, so to Canon and their image, it’s worthy of the title flagship. Their flagship Camera geared toward one of the worlds highest grossing and content consuming industries.
Flagship meaning: The best or most important product, idea, building, etc. that an organization owns or produces.
This definition doesn’t describe what a fragmented segmentation of people want; a jack of all trades master of all product for less than what it would cost to produce. If Canon produced such a camera that was capable of that spec wise, it would be priced astronomically high and they most likely wouldn’t see a positive return on their investment.
When I was a professional wedding photographer, I never invested in any of the 1 series cameras because they either didn’t do what I needed, or they were loaded with extra features I found useless. Cost was never an issue, as it was always simply a matter of finding a piece of gear that suited my exact needs and buying it. Easiest thing to do in the world, as opposed to wishing for a different piece of equipment to be something it’s not.
So, tl;dr Canon knows exactly what they’re doing with the R1 and R5II, and they’re both designed ideally for different segments of the market. They’ll sell well for those that’ll utilize it, and it majorly bolsters their brand image further. This is flagship stuff for them.
Hey, if I’m wrong and the R1 and R5II tank, I guess Canons next earnings report will put them in the doomed bracket.
