Crewdson revisited
Ok, I stumpled upot this great polish site, where they have high resolution exelent quality scans of his work. Enough to make 6x9 prints (and I'm going to do just that)

these are two examples
At this size the images seem a bit different. They look more realistic. The smaller size images looked more painterly, while in this size it looks more real.
At this point I'd say this looks like HDR to me.
Gregory is known to make houndrets of exposures for one image, throwing away some sheets, while combining the rest of them in one image. He does a lot of pasting together, so naturally using HDR would not be much of a suprize because he pastes multiple images into one anyway.
It has this flat, yet not washed out look. Sort of like every object has nice punchy contrast, yet different areas are flatened out together as if they are all of the same exposure. This is typical of HDR imaging.
I don't do HDR myself, but I've seen some of the HDR work on the internet, and it really looks a lot like this.
But of course, now, at this size i can see that 80% of the look is in the lighting. It's amazing what this man does with lights. It seems like he controls every little shadow in the picture, even in outdoors, he must have rigged an entire streets with lighting for this stuff.
So this is my final theory, you tell me does it make sense:
He sets up complex lighting, just like on old movie sets. He shoots many images, many different exposure settings, many lights on-off (like motion control work in movies), then some with people in the scene, some without people etc.
Some of the lighting as it is rendered would require missing lights that are not there in the image, so I think he lights all these objects in different sheets, then erases the lighting maybe when combining with sheets where there is no such lighting. For example putting a flash in front of a person, then copying that area from a sheet where there was no flash, or maybe not even the person etc.
Then he merges the environment into this HDR landscape, then he puts people/cars and everything else that maybe required separate exposures.
Then he enhances the skintones a bit on some images by some basic retouching tricks to get a more fantasy-like falloff of light onthe skin, typical advertising retouching, but only subtle I think.
Then he enhances the saturation globally and whoila
Does that make sense?
