So, a FF back-lit CMOS sensor ? ? ?

ROFL  ;D ;D ;D.

This so called "source" has no clue about what's going on in the semiconductor industry today.

"Doubles the sensitivity of the sensor"

Does that mean they will be going from 3200 tops to 12800 tops? Or does it mean 2 stops improvement in noise performance? What exactly, I wonder...?

That would mean going from 3200 to 6400, if you take it literally. AKA a single stop noise performance.

But there is always the possibility of Canon making simply a certain range of settings available, and the true change is in image quality.
Say the sensor creates 1/3rd of the noise. this could translate to one stop higher settable sensitivity with improved noise and shadow rendition, or an additional H-setting with worse characteristics.

But being backlit wouldn't help a large sensor as much as it does for a small one, I wouldn't expect wonders without taking hints from the 1DIV's design. :)
