My RF 800mm f/11 is just as sharp as my last EF 400mm DO ii with the EF 2xTC at f/8 as is the RF 200-800mm at 800mm f/9.

Well..... Nikon in fact did:
AF-S NIKKOR 180-400mm f/4E TC1.4 FL ED VR
It's true that Sony hasn't, AFAIK

Wasn't aware of that lens. It came out 5 years after Canon's, so does that mean we can expect Canon's integrated TC primes in 2027?

Maybe I am lucky... I don't have big whites but my underwater gear adds up and I need a hobby! My other hobbies cost me nothing.
My global insurance premium is itemised and sitting at 2.7% of replacement value. Not a lot of GAS for some time now except for maybe a fast/wide prime if/when it ever shows up.
Handbags are also expensive!!

Another one who is behind the times: we have same-sex marriages here in which, good for them, they describe themselves as husband and wife.Just corrected that for you....

Just corrected that for you....
And there's me thinking this was a thread about the EF 400mm DO IS mk II's replacement....and suddenly it's all about gender politics and pro-nouns.

Here's hoping!
However, in reply to your three points:
1) yes I agree, although just as inconvienient if you want to use a 2x TC.
2) The EF lens from 2014 is equally as sharp as the latest / current RF 400mm f2.8 LIS. Revision is no guarentee of "more sharpness".
3) We will wait for that assumption to be seen. Adding a chunck of 1.4x tc flippable optics and supporting material isn't going to be light and could easily make this new RF lens as heavy as the old EF lens. I'd hope for it to be smaller and lighter....but you know...it's a Canon RF super white tele. Canon have been under-investing in these for quite a few years now.

Nikon has had 200-400 f/4 lenses for a long time before Canon (the latest one is the 3rd version), but Canon was the first to add an integrated TC.
Only Canon knows

We do not know the long-term fate.
Primes would still be lighter and cheaper.

It is a completely different class of lens.
Nikon later made a 180-400 f/4 x 1.4 to compete.

IMHO the patented RF 400-600 f/2.8-4 would be far better than an RF 400 f/2.8 with a built-in 1.4 extender.

Seriously though....I am very temped by that nice 400 f4 DO II over on MPB at the moment!

However, I think Nikon were the first to make a 200-400mm f4 lens and Canon took forever to get their's to market. When they did...it has the 1.4 TC flipper, whihc was a bit of a revolution at the time. canon's version wasn't as popular as Nikons partly due to pricing. Then nikon did the same with their, put a 1.4x flipper in it and charged a pile of cash more. It's a classic case of each brand inspiring and leap frogging each other. We as customers sometimes sit back and munch the pop corn and say...wow...look at that!
I think it's ironic that Canon were the first to put image stabilisers in their super whites. the first to paint them white too. The first to do the flippy 1.4x TC, the first to use diffractive optics, the first on so many fronts. I think they invented the 400mm f2.8, 500mm f4 and 600mm f4 too. But these days, they seem a little complacent and Nikon have a lot more 400/500/600mm offering. Some with flippy TC's and others with DO elements.
