I read that it was so they didn't have to re-design/engineer the camera housing itself. I would only use it with SSDs anyway so no big deal for me.

Because this:
12K – 12,288 x 6480 (based on 24p)
Blackmagic RAW 5:1 – 578 MB/s
Blackmagic RAW 8:1 – 361 MB/s
Blackmagic RAW 12:1 – 241 MB/s
Blackmagic RAW 18:1 – 160 MB/s
Blackmagic RAW Q0 – 241 to 578 MB/s
Blackmagic RAW Q1 – 144 to 361 MB/s
Blackmagic RAW Q3 – 96 to 241 MB/s
Blackmagic RAW Q5 – 72 to 180 MB/s
The beauty of shooting on SSDs is editing right on the drive, no copying. I know that strikes horror amongst many, until you get hooked. Then it's a drug. But nothing stops you from copying the BRAW files somewhere else, a slower disk drive for backup. You're not giving anything up or taking unnecessary risk. Edit on the Superspeed USB 3.1 Gen II SSD. Let's be real. For me, paid shoots are typically not BRAW, not 12K, but collaborations with others, so prores, XAVC etc., usually on SD cards. A lot of raw for me is experimental, stock footage. It's more than appropriate to save a step and time by editing on the same SSD I shot the footage on.
A file system? For a direct copy to an editable drive? So that you can edit on the same disk later? With BNC, aren't you just streaming raw data that has to captured on the other end with a recorder? You end up with a file on a flash drive just the same but the card reader you would use to transfer the file is not in itself fast enough to edit on.
Unfortunately, there is not a simple answer to this question as a lot depends on the demosaic approach to eventually reconstruct full RGB information for each pixel.
A typical 80 megapixel Bayer pattern sensor would have 20 MP of red, 20 MP of blue, and 40 MP of green photosites (used in part for luminance). An RGBW color filter array with 50% white (clear) pixels would have 13.3 MP of red, 13.3 MP of blue, 13.3 MP of green, and 40 MP of white/clear photosites (used for luminance). Which means that there are the same amount of red and blue photosites as in a 53.2 megapixel Bayer sensor. And the same amount of luminance pixels as in an 80 MP bayer sensor.
With both Bayer and RGBW sensors you are effectively subsampling the color information and then later using that to try to reconstruct the original per pixel colors. This is essentially a form of image compression. And so how close you get to the full per pixel color information depends on the compression and decompression (demosaic in this case) approach used. So you can't really compare the perceived resolution of the sensor in isolation, you kind of have to compare the full image processing pipeline result. For example, a poor demosaic of a Bayer sensor in some cases could give you a worse result (from a color accuracy perspective) than good demosaic of an equivalent megapixel count RGBW sensor, even though the RGBW sensor captured a bit less color information to start with.
When it comes to how our eyes perceive image resolution, luminance information tends to be much more important than chrominance (color) information (this is why 4:2:2 and 4:2:0 chroma subsampling approaches are so effective). Since an RGBW sensor has the same amount of luminance information as a Bayer sensor, I would expect that the perceived resolution of both sensors to be pretty close in most cases.
And since the clear (white) pixels are up to twice as sensitive to light as green pixels, they have the potential to improve low light performance of the sensor overall (somewhere between a 3 dB and 6 dB improvement in signal-to-noise ratio depending on the amount of available light).
Image Algorithmics has a pretty good FAQ regarding resolution and and color accuracy differences between Bayer and RGBW sensors, as well as the sensitivity advantages on their website:

RGB F35 is considered a 2K camera with its 6.6 MPX sensor. BMD 12K is 40MPX of RGB, 6 times of F35. 4K is 4 times of 2K. So, my interpolation is that this is an RGB 4.5K camera with a decent but not outstanding low light performance.
Of course, when F35 came out in 2007, it was the state of the art in imaging technology and selling for $250,000 retail.

Previously you lost the only 12G SDI for the SSD, i.e. you could only check HD instead of 4K (Which sucks if you have something like Atomos Inferno and want to pixel zoom check focus, or actually monitor with 4K screens on set). Why do you need the USB-C when an SSD-recorder is attached? You want dual/tripple recording (cfast, SSD bolted on the back and SSD from USB-C)? I don't think anyone here is saying it is "good" that the USB-C is lost for SSD, just that it is better than previously. I personally would love some SSD or M2 slots, but I get it that they are stuck with the same body and basically the same engineering and thus crappy Cfast remains.

Hi, there are two USB-C ports on the camera. One on the rear (thankfully) and one behind the camera door. I'm not certain if both are latest standard, I'll be trying out some NVME enclosures soon as I think these are a great and affordable alternative to CFast.
As a random side note: I was able to shoot 12K Q0 to my old 64GB Lexuar SDXC II (300/MBs) Card without frame drops. I can't find my 128GB Sandisk to try it out.
There are a lot of options for recording media. Cfast may not be the best, but I don't think most people will necessarily require faster speeds, especially as most will shoot 8K or 4K.

That's hard to believe. Surely that can't hold up for fast-changing, detailed shots or longer record times...

Oh, good that the old USB-C is still there. I never used the USB-C on the G2, because really bad to have the LCD-screen open when doing gimbal work (I just took the bullet and bought some Cfasts). So much better now on the 12K, but if I get it I guess I will just use the back USB-C and not bother with the SSD backplate since it builds it too big for gimbals.

I’d be very surprised if the Komodo has more than a single stop of DR over the BMPCC6K or ZCAM. Also, the PL mount on the UMP12K shows exactly who their target is, and it’s not anyone wanting an RF Mount. I’m willing to bet that this camera will steal the crown from Red in the VFX world.

On paper!!!!!!!!!!
Yeah. I mean in my experience Monsto doesn't have more dynamic range than Alexa, in the way I like to shoot and test anyway. And yet on RED's site, it's a 17+ stop camera.
https://www.red.com/dsmc2
Arri ? they say 14 stops on their website.
https://www.arri.com/en/learn-help/technology/image-processing
There's a MASSIVE difference between 14 and 17 stops....Anyone else think those numbers are right ?
This is why I detest using "stops" as a way of measuring dynamic range. They're always a BS number unverifiable and totally subjective. Complete with non-sensical unscientific phrases like "usable" to "bankable" stops
