This is false. Market domination is definitely relevant. It's the reason people who want the absolute best gear switch brands. With the new raw compression canon has, the raw files from my 45mp r5 are between 15mb-25mb, smaller than the raw files from my sony a9ii 24mp camera. They could have definitely made the R3 30mp and made it slightly more future proof. In it's current state(and assuming it is $6k) it will be a pass for a lot of people who would have otherwise bought if it were 30mp-ish. The point of higher MP is cropping ability which translates into extra reach if you need it. Very few people will actually print a 45mp image.

A 400mm f/5.6 requires an element of not less than 400/5.6 mm, ie 71.4mm so you can't have one with a 67mm front size.
Read the second half of the sentence you quoted.
RF 16 2.8 with 43mm filter ?
I think this is an EF-M lens or a lens for an R APS-C camera.
Or it has 5+ stops of vignetting at f/8.
The smart money says #3. Just look at how every other recent wide-angle Canon lens operates, and multiply that by how every other manufacturer compromises on optics to create compact lenses.
They're not going to announce APS-C RF (not R; that was a Canon mount in the early 60s!) lenses until they have an APS-C RF body to show, and given how all of this has leaked out well ahead of announcement but a body hasn't, it's safe to say there's no APS-C RF body on the horizon.
EF-M is basically abandonware at this point. Nobody should expect any new EF-M products. I'm not going to go as far as to say Canon have formally shuttered the product line—they still have existing stock to sell—but they're clearly not working on any new products and are only paying the current ones lip service. Once the RF line has moved on to the point the original RP can be priced at under the £800 mark (which may be as soon as the next year) I bet they will then officially call quits on EF-M. There's no point competing with themselves.
RF 16 2.8 with IS would have been great for video and vlogging
with e.g. an RP ... but maybe that is a non-market-
The handheld video market mostly buys zooms, and Canon have the 14-35mm f/4L IS that they're trying to sell people on. As woefully overpriced as that lens is, they still seem to be pushing that as some kind of 'bargain' as well as the lightweight video option, and they won't undercut that advertising with a cheaper and smaller lens like this. For the people who want even smaller, lighter and cheaper, they still have that leftover EOS M-series stock to get rid of.
What I expect is they'll show it doing video on the R6 or R5, then they'll show it being used for street & lifestyle photos on the RP. That way they can show how small it and the RP can be together, while still implying it can be good for video without having to acknowledge the lack of stabilisation. Canon are very experienced at showing new products in
very specific ways to maximise implied capability without admitting the realities of those uses.
