Regardless of where the numbers fall on what resolution Red "really" produces...
You have to be impressed with the marketing department guys who can say, "Their sensor only produces 3.5K! Our camera produces a full 1.92K," with a straight face.
How is that better?

Lee, that's exactly the point. We say what the sensor is and what the measured resolution you can expect to get it, post decompression once you've gone through the whole RED workflow. Neither do we count resolution that's obviously aliased rather than real resolution either.

This is soo fun
I have litelarily heard:
"Well ours doesn't do fully 1080 because that's where it starts, but look at RED, they don't even resolve 4k."
Usually when I mention that it undoubtedly resolves more than full 2k/1080, I get the fanboy glare...
Until we sit in post...

If we resolved 4k on a 4k sensor, we'd be aliasing badly, and that's ugly and makes compression for broadcast hard (because aliases confuse motion adaptive codecs). It is vital from an image quality and solid technical engineering point of view that you never try to measure the same as, or nearly same as resolution as you have sensor size.
We can take Jim's drawer analogy and instead of it being full of socks, let's pack glass baubles in it. That's your resolution, but pack in too much and when you shut the drawer - they can break, and that's your aliasing. The OLPF is a nice fuzzy bit of padding you put in the drawer to eliminate accidents from all but the worst job of over-packing.
So that's why you want a few less baubles, which is fine because you have oh-so-many of them, rather than a lot of broken glass in the bottom of your draw.
