Canon has announced a C-series 4K (PhotoJPEG 24fps) DSLR in development, likely coming out in 2012. That's what I'm talking about, not the C300.
They had the fixed prototype out last year (at Cinegear etc) but not the interchangeable one.
This thread is not about the $5K cam.
It's about the $10K interchangeable cam (hence the words "~$10,000 large sensor interchangeable lens cam" in the subject!)
Um... "broadcast spec" will very, very likely be 4K @ 60p... and Scarlet-X can only do 60P that at 2K
Sure, films may still be 24 (except Hobbit at 48 and Avatar 2 at 60). But "broadcast spec 4K"... 60p, man.
Also, the Scarlet can't output 4K in realtime, so you can't "broadcast" live from it at any frame rate.
Scarlet-X is awesome... but it's not a "4K broadcast spec" camera. Hopefully they will make a module in the future that can realtime debayer at 4K and output HD-SDI 4G or HDMI 1.5 or whatever (HDMI 1.5 looks like it's going to be announced sometime later this year)... but I'm not sure if Scarlet will ever do 4K 60p. That's actually what knocked it out of the running for me.
JVC's camera seems closer to what an eventual 4K broadcast camera will be (once HD-SDI and HDMI catch up and don't require 4 damn cables). Sony's weird "rotated Bayer" sensor looks like it will easily debayer in realtime to 4K so I imagine that they will have a range of cameras with realtime 4K 60fps output... hopefully Panasonic (and eventually Canon) will follow suit in making 4K 60fps broadcast cams. IMHO, >24fps is where you really see the 4K difference. Otherwise, it's mostly a bunch of high-resolution motion blur with the occasional nice-looking landscape shot!

I don't know of a 4K broadcast spec yet, though I think you will probably be right about 60p being included in some form.
For downres from 4K Red RAW to 1080p, the Red Scarlet-X
meets Current 1080p broadcast codec specs anywhere on planet, as far as I've heard.
Ultimately, I assume the next HDMI standard (V1.5?) being finalized later this year
will accept 4K 60p signal over a single cable, as well as 3D, hence making JVC's current offering
an interesting sidenote, as was their original "HD" camcorder.
I think JVC history will repeat itself in this regard...
