Might have missed it, but I don't recall any mention or estimates of the what anyone expects the native ASA of the AF100 to be. Does anyone have an idea?

It hasn't been settled yet. When I was using it, it was set at about 400.
Setting the "native" ISO is a matter of them deciding the best balance between sensitivity, noise, and dynamic range. As the imaging system isn't done yet, that fine tuning hasn't been performed, so the "native" ISO isn't established yet.
When in FILM CAM mode, you can select any ISO from 200 to 3200, in 1/3-stop increments, so you'll be able to choose your own ISO preference. In VIDEO CAM mode, the "native" ISO will be whatever it's set at, at 0dB of gain.

Very cool. That was one feature I've gotten very used to in DSLR shooting. I'm sure it's too early to know, but any idea what the max ISO is before noise?

Way too early to say. There's noise in every ISO on every camera; it's a matter of personal taste as to where you say "ugh, that's too much"...

That's a good point. I found that 6400 ISO on my 5D still looked better than Gain +3 on my XH-A1. So yeah, the question would be what is the limit for relative noise-free shooting. Obviously a max of 1600 ISO on the 5D gives you a fairly clean image.
And also, what does the noise look like? Nikon managed to have a monochromatic noise in their HDSLRs which gave it more of a film look. Barry, did you see the noise at all to know if it was the typical color noise seen in most video cameras?

It is definitely not the chroma mush that many other video cameras and DSLRs give off. It's a very fine-grained luma noise.

That is some very good news.
