CMOS vs CCD

Recently RED and the SI-1920HDVR claim to offer really high resolutions using CMOS sensors. On the HVX200 board, I heard someone say that a CMOS looks way more like film.

Untill recently I had never heard of a CMOS chip. When I did hear about it, it was always as a cheap alternative to CCDs and that it produced more noise and a less pleasing image.

If this is the case then why are these supposedly way better cameras using them (and in the SI-1920HDVR's case, only 1). Is the single chip perhaps the reason I find the colors a bit disapointing compared to the HVX200. For that matter, is it likely that one of the reasons the HVX200 looks better than the JVC HD100 color wise (aside from the 4:2:2 sampling over 4:2:0) because it has 3 CCDs instead of just one?
 
Note: JVC HD100 is a 3 chip camera (3x 1280x720p sensors), you are thinking of the HD1 and HD10, those where single chip.

The stop end camera, Dalsa Origin, Arri D20 and Genesis all use single chip designs, so 1 or 3 chip isn't impacting the color flexibility. The SI1920 images are all untweaked, adjusting the camera's curves and color matrix will pretty much alter the look completely. I'm sure in the coming months SI will fine tune to create some nice presets.
