You seem to have been posting throughout the night ! I'm in England, it's 10 am here, a much more civilised time for posting

Sure. As I've said, I have nothing against the concept, at all.
I truly, honestly believe that does Foveon a disservice. Not everything is about megapixel count.
Sigma should be marketing their DP series of cameras on the STRENGTHS of Foveon, instead of fabricating fanciful "megapixel equivalency" numbers and the like. They are undermining Foveon that way, when it IS such amazing technology.
If you were being honest here, you would own one yourself. You obviously are trying to have it both ways, trying to appear unbiased. You frankly have everything against this concept, when it comes to this manufacturer. Admit it, you don't like Sigma as a company, you would not buy any of their lenses or cameras. But The difference between you and me is, I've owned a foveon camera, the one with the sensor you deride most (and I currently own 2 Sigma lenses at the moment). It simply had more resolution than its native 4.6 MP dimensions...I'm sorry but it just did. You can rely on math all you like, but the proof is in the using, and viewing. To say that it only had 4.6 MP of resolution is utter nonsense. Plenty of reviews have backed me up on this.
As for the Quattro sensor, I have no idea why it has fewer photodiodes for the other color channels...but frankly, if they are making the camera produce a 39 MP jpeg, then logic would dictate that it is resolving at least somewhat more than 10 MP.
With a bayer array, you don't have 18 MP of all three colors of photodiode in your 7D. You have far less than that. And yet you're happy with the results you get.
Again, the proof is in the using, and the images, and less so the math. Math can be used to predict things like a rise of 10 feet in sea level over the next 20 years due to that nasty old capitalism, but how accurate, honest, and complete is that math?
if my 5D mark III will suffice to extract the most detail from those incredible landscapes.
If you convert a bayer sensor's data to monochrome, you effectively have just the full detail luminance.

You hand held a 600 mm focal length at 1/30th?? Amazing IS. Does the 50% size stand up ?
Yes, and you can click on the photo (the original one, above) and view the EXIF if you have a viewer - I use FxIF for Firefox - if you don't believe me
My technique for still (or relatively still) critters in low light is to get the shot, then start dropping the ISO until I can't get a sharp photo. ISO 1600 was that point for me, and I also fire off 3 or 4 frames as the shutter speed drops in the hopes of getting at least one sharp frame. My rate was 2/3 frames at 1/30s so yes, the IS (mode 3) was working brilliantly! The owl was up really high so even at 600mm I had to crop a lot (final file is only 1622 x 2433) The 50% zoom holds up decently well - probably good enough for an 8x10" but that's probably the biggest I'd try to print it. I have attached the 50% zoom below.
but I snagged him with my 300 + 2x with (OOPS!) circular polarizer. It was dusk but I didn't think it was THAT dark! Luckily the IS allowed me to handhold at 1/30s
when taking the same photos with my friends, it appears my 5D lacks image quality compared to their fujis & sonys.
Here's "Smiley" (named Smiley for what appear to be rows of teeth on his jawline)
First image Smiley....second image Smiley with distracting nearby "scenery" that almost caused me to miss the shot!
Incidentally the 85 1.8 is not sharper than the 40.Interesting. I must just think it is because shooting outdoors allows me to lower ISO and stop it down a little. Or maybe the contrast between in focus subject and blown out background makes the subject "feel" sharper than it really is.

It might be for the OP, if it needs a focus adjustment (which cannot be done by the user with a Rebel/xxxD body).
