To address your F23 rant, though: I don't think the debate is quite so cut-and-dried. The Genesis actually uses a big chunk of Sony imaging technology, so rather than the F23 being a 'cheap Genesis knockoff,' it's more like a different branch from the same tree. And although the Genesis does have an impressively-sized chip, it still (as far as I know) translates into the same ho-hum 1080 resolution. Mainly, it was developed to be usable with Panavision lenses, which is definitely terrific, but I don't think this makes the Genesis an inherently superior camera to all others. Most others, yes, but not all. Now, if it could use Cooke S4s, I might change my tune....
As for the D-20, it would be mind-bendingly magnificent, outstripping all others (even the Genesis), except for one teensy problem -- all the good stuff is only available in 'data' mode, which is still unavailable! I mean, come ON! Nice idea, but I'll reserve my confetti and party hat for next year, when the data mode will presumably be fully operational and the D-20 can show us its full range. Until then, pbthfthfthft. And that's the technical term, I believe.
For my money, it's the the Dalsa Origin which currently kicks the most ass -- depending on how you capture, it has what I like to call 'hyper HD' resolution, plus it uses 16-bit instead of everybody else's 12-bit approach, so it has a latitude of about 12 stops. W00t!
I suspect the RED camera is a whole lotta hype, but I'll hold my judgment until it's fully
As for the F23, it has full 4:4:4, and the highest rez is the blah de blah 1080 (snore), but get this: it has 14-bit capture, which definitely makes me curious about its latitude. I fully intend to badger the Band Pro folks on this, as well as about lenses/depth of field/variable frame rate (I'm not so hopeful about that last one), we'll see what happens.
In case you haven't seen this, I strongly recommend the downloadable chart at http://www.hdcompare.com/Cameras.htm. It doesn't mention the D-20's belated 'upgrade' next year, but it's otherwise pretty impressively comprehensive.
