THIRTEEN GRAND???? … for a measly 600mm lens, huh, WD?
I say - is that thing made of gold, or what?
So, listen, WD … is that 150-400 an OIS lens, or not? … What's that, in effect - 300-800 (FF equiv.) ???

That is correct. With the built in 1.25X teleconverter it becomes 375-1000 (FF equiv.) and ~f5. I suspect since they are not changing the optics that much with the 1.25X, I expect it will be very sharp to extremely sharp at that range. Without the 1.25X, I expect it to be extremely sharp like the 300 f4 Pro IS lens. And, of course, it will be weatherproof. One will be able to go shooting in the rain and only need a towel to dry off the lens when finished shooting. I am sure there will be image loss with the use of the 2X teleconverter, but hopefully it will remain very sharp. I am hoping Olympus might have a prototype copy at the E-M1X launch event here in Denver. One of the other lenses I hope to see is the 12-200 f3.4/6.3 Pro lens (24-400 FF equiv.) but it is not IS. Because it is not IS, the price is ~$900 compared to the $1300 for the 12-100 f4 Pro IS lens. I am still inclined to favor the IS over the excellent increased range (IS is that good in shooting value). I want to see what Image Resource finds in image quality before passing final judgement.

That G85 is an exceptional package! DP Review loves it. It’s very well-rounded, well-built, and the design is excellent.
I am not sure either Panasonic or Olympus would put out just a good camera. They have all been top of the line for their market at the time of their release.

Also, the equivalent angle of view comparison is as follows:
Canon EF 600 f4 IS mrIII = $13000
Olympus 300 f4 Pro IS = $2500
And and we could discuss the smaller size and lighter weight (easily handholdable at under three pounds without the tripod mount) of the Olympus. Image Resource's comment was that they knew the released Olympus 300 was going to be sharp, but they didn't know that it was going to be that sharp. It is a truly incredible lens worth every penny.

What about DxO Labs, WD? … I thought they were the final say in all lens matters (here, anyway.)

Well, WD - if you don't mind putting out two-and-a-half grand for a lens, WD … all power to you.
I even balked at paying that kinda money for a new fridge!!! … And, that's 50x as big!!!!!

Sometimes you've got to pay to play...but this comment from you doesn't surprise me as you're still using dial up...seriously, it's time to upgrade.

Now the Nikon Z6 and Z7 have appeared with built-in IBIS, joining the crowd of cameras which incorporate it - mainly those made by Sony and Pentax, along with all Olympus MFT models, and some Panasonic MFT models - many of which are said to have "Dual ILIS" - we are faced with a conundrum of sorts. Where do we implement DUAL ILIS - in what situations? … And, what problems are we likely to encounter when we do?
ILIS is clearly superior in longer lenses to IBIS.

Technically it's better to have them working together...if your camera supports it. No way at this point would I give up my EM1ii IBIS.

There really is no downside (that I know of) to using IBIS, ILIS, or both in combination, although as others already pointed out, IBIS can be more effective than ILIS (or the other way around) depending on the lens type (short vs. telephoto).
Manufacturers advise to turn off the IS when using a tripod for best results. This is all I can think of.
