Maybe something is coming, but whatever happened to that 300-600/5.6 that site was talking about? i don't think they are very reliable until the PR is imminent.

Last, I recall reading, that lens was being tested in the field, but that was at least 6 months ago.

If true (new 39Mp fully stacked BSI APS-C sensor) I think that would be a significant step up from what many would have expected from Canon, and it may indicate they are moving the R7 II more up-market.

Good news for most of us, I would think.
It's a step up from anything available for APS-C from anyone. We have high-speed full-frame and high-speed MFT sensors, but no high-speed APS-C sensors.
And a big part of this is that it could be just as revolutionary for video as it can be for stills. I hope Canon leans into that part, as that'll move units and keep the segment viable!

The Fuji X-H2s has a 26MP stacked BSI sensor. It is a really nice sensor and has about the same sensor scan speed as the R5 II. A 39 MP sensor would of course be notably higher resolution, but Fuji has that pixel density in a non-stacked BSI APS-C sensor in the XT-5, XE-5, and the XH-2, so making it a stacked sensor would be a solid move forward, but I would think it is possible. I would expect when Fuji makes an X-H3s, it would have a similar sensor.

First Sony has to be willing to make such a sensor - and we've seen how they've let APS-C languish. Nikon has the same problem, as does Ricoh if they want to update any of their or Pentax's dinosaurs.
-----------------
The perspective I'm coming from is that there really isn't a 'step' between MFT and full-frame here, nothing that would rival the better hybrid cameras from either system, and that's in large part due to the lack of a sensor to build around.

Well there is the Fuji XH-2s. It has the 26 MP BSI stacked sensor. That is a sensor to build around and Fuji has done a pretty good job with that camera. See Morris' examples here of what it can do in capable hands. Like I said above it has the sensor scan speed of the R5 II. It can shoot 40 fps (but does better at 30 fps). Fuji's AF isn't quite up to Canon's but it has improved and especially so with this camera. If you want a step between m4/3rds and FF, this camera is it for now.
I do think an R7 II with a stacked BSI sensor would likely be a better camera and likely better than even a new Fuji Xh-3s, but no one should think that Sony won't build a stacked sensor APS-C sensor--they already have. I don't think they will put one in their own camera, but I think they are happy to build one for Fuji and they would build one for Canon too if Canon wanted it.

Fuji's AF is the main reason that I exclude them generally, but also their wacky product segmentation. One of the things that attracted me to Fuji (and does again on and off) is their lens lineup and availability of weather sealing; but the thing that keeps me from biting is that it is inconsistently applied, and that a great many of Fuji's lenses - especially zooms - appear half-baked, while a great many of their primes are woefully out of date optics wise. Oh and the gating of IBIS.
Like I'd have already jumped if I could get a compact setup with WR and IBIS, but having those be inconsistent and having inconsistent AF just sours me on the system.

Yeah, I should have added (and meant to, sorry!) that I mean 'in this resolution class'. Though I think that the Sony sensor is actually pretty nice and far better than the aging 24MP APS-C sensor Canon has been using too.
As for Sony putting one in a camera - honestly I'm pretty sure they would if they built the sensor. People still buy their APS-C E-mount cameras, and if the sensor is also good for video, I'd expect Sony to build a decent hybrid or even a cinema camera with it.
Canon led the industry at 32mp back in 2019. The R7 II could easily push their lead further.
As far as BSI and rumors in general:
"I think I can give some great news with a good level of confidence. The EOS R7 Mark II will have a backside-illuminated stacked sensor. This will be the first for a Canon APS-C camera. I don't think we'll see this specification on any other APS-C camera from Canon this year. It will be a 7 series exclusive for a while at least. Nothing is a 100% ahead of an official camera launch, but this is the first time I have a level of confidence to write about it."
The rumored R7/2 is the first Canon crop camera to interest me to the point of buying since the SL2. If the sensor is as advertised then I am very likely to buy one once I see if the reviews for it live up to the hype.
Looking forward to seeing if this materializes. Would be a pixel per duck monster.
39MP with Canon's 1.6x APS-C is the equivalent pixel density of a 100MP FF sensor!!!
As long as the IQ/noise handling holds up it could be an excellent companion to an R5II or R1 when you need maximum pixel reach.

To be fair to Fuji they already have a 40.2MP APS-C sensor (2022). Although because they use a 1.5x crop and Canon uses 1.6x a 39MP R7II would take the record for pixel density.

Yes, fuji passed them in 2022 now Canon answering, more of a speed oriented camera, it looks like, roughly the same amount of pixels.
Sony and maybe Nikon still 26mp haven't caught up to Canon though.
One of the main reasons to get an RF-s body with tiny pixels is to gain reach with big teles.
From what I can see Fuji X has no big teles (100mm or larger front aperture), only a few slow, long lenses (100-600/8 and 500/5.6). Fuji X is more about retroactive-looking compact body styles and small lenses only for APS-C, since they have no FF.

Of course Fuji also has cameras with 44 X 33 mm senors, with sensors that are notably bigger than FF. Those are IQ monsters, but do not shoot quickly. Fuji has left high speed shooting to the X-H2s, which is a fairly capable camera. It has a 26 MP APS-C, same pixel density as 60 MP FF and has a stacked sensor and shoots 40 fps. It actually has higher pixel density (pixels per duck) than any FF stacked sensor camera. The camera's AF isn't up to Canon or Sony or really even Nikon, but it isn't terrible either. You are right they don't have any lenses with an exit pupil larger than 89mm. Wildlife shooting is mostly relegated to the 500 f/5.6, which has two different mounts, a GF mount for the 44 X 33 sensor cameras, which can produce excellent results if you can get close enough and the wildlife isnt moving too fast, and an X mount primarily for the X-H2s. It can produce really nice wildlife results as Morris often shows in the wildlife forum, but it does not have the capabilities of the high end FF lenses from Canon, Nikon, and Sony. It is especially limited when light levels are lower.
