Depending on the sensor technology I think we won't need an AA filter for 75 mp in a full-frame sensor size. Using the Bayer color pattern, that is fairly close to the optical limits. Diffraction might eliminate the need for an AA filter. I think some cameras now come without an AA filter- one of the 5D lines, I think.

Larger than full frame, an AA might be helpful.

The red and blue channels alias quite a bit with the size of pixels in a 75MP FF and commonly used f-numbers with a Bayer CFA. It's not just a matter of half the sampling frequency in those channels compared to the luminance; they don't have box filters, because they do not border each other, but have other colors between them.

These sensors seem interesting-

I didn't have the silicon know-how to implement the 1-bit sensor, but I thought of the geometric/photographic idea years before I ever heard of the QIS work. In fact, I was ridiculed for the idea in the early 2000's on Usenet's alt.photograhy.digital by one of the foremost digital imaging experts of the time for suggesting that the ideal sensor would detect just one photon in each photosite in billions or trillions of them. His silver bullet to my idea was that a maximum signal of 1.0 means an SNR of 1.0, and therefore, 0 stops of DR. This guy missed the image for the pixels, he was so wrapped up in the sample-centric math and ignoring the practical meaning of its application..

It really doesn't say anything new IMHO,. other than that the RF may be even better, but Canon has been consistent in it's stated reasoning for NOT including IBIS all along.

In short, Canon has always claimed that in lens IS is "better"

That the RF mount offers even more room for in lens IS improvement does not change the claim.
I have never debated the claim, but would still like to see IBIS for all the lenses that do not have IS built in.

I was playing yesterday with my A7R3 and the 24-240 OSS and my EOS R with my 10 year old 70-200 f4 IS. At about 200mm, the Canon was far more stable just through the viewfinder. I think Canon knows what they are doing.

I'm slightly amused at this point that I own 5 EF lenses and I don't own a single native EF mount camera anymore. I have 3 FE lenses and an MC-11. 2 RF lenses and an RF adapter. Then 3 EF-M lenses and an EF adapter. Honestly it makes more sense since I can use the EF lenses on any of my bodies.

I've actually considered selling off my EF lenses for a simple reason, the RF mount. Although I'm shooting Sony now, I am sure I will get a Canon body in the coming years and I feel it might be best to sell it all off and replace the lenses with RF versions before the value drops on EF lenses.

I have the same thoughts yet I keep buying lenses. Lol

Irony being the last part of his statement. As the prices of EF lenses are certain to go down. I hate dilemmas. Do I quick kick or do I wait and punt?

I did pre-order the RF 24-105L a couple of days ago just to have one native/designed for lens. The 35 is pretty attractive for the price and it's a macro to boot. Never owned a prime outside the Nifty Fifty and the EF 40 pancake. What to do about the 35? I can't afford the 50 or the 24-70, as much as I'd love to have either or both.

I will say this. The CR adapter has breathed new life into my EF and EF-S lenses. Amazing really. These lenses are much better than I even ever thought. Thinking it has something to do with the micro adjustment thing I never bothered to do with anything else I have ever owned and is unnecessary with the R. Maybe there was something to it all along after all. :-D

I have the lion's share of lenses that I really need for RF and EF bodies. The RF 24-105mm is one highest on my want to get list. As for future prices of EF lenses, that's something I curious to follow whether or not I buy any. I'm guessing some will drop and some will hold value. For example, the 85mm 1.2 works even better on the EOS R, and if Canon doesn't make an RF 85mm 1.2, I can imagine that prime holding the same selling price. Maybe like the Canon EF 50mm 1.2, the price could rise.

I guess it's a bit of an experiment for you then! I wonder when they will replace the 100L with an RF version? The EF version is hitting 10 years old now and is popular so I think it could be updated sooner than later.

Just guessing but I suspect 16-35 and 70-200 relatively soon because they are so widely used. I might go for the 16-35. Eventually 70-300 and 100-400. I might go for either of those but don't really have to because I have the 28-300L and 100-400L in EF.

I've believed ever since this announcement that the 70-200 III was more about a prep for the R than anything else. My bet is it's nothing more basically than a mount change at this point. I think they're just waiting on production and some grandeous moment to announce it. Surprised it hasn't been spotted in the wild to be honest with you. Maybe it has. After all, the adapter is so small, someone would really have to be paying attention to see it if somebody was under NDA.
