I think that DR will improve by only 1/2 to 1 stop over the current model. They haven't built a new sensor fabrication plant
they don't need to.
No, they do not. They can convert an exist fab process in an existing plant. It's already been done. The C300II has on sensor ADC.

you don't need a new fab, just an improved process.
For memory etc the key is to have ever smaller geometries, which could easily mean a whole load of more precise machines.. essentially a whole new fab. For imaging chips you need process purity and odd processes that may add superior optical or analogue features, pixels have gargantuan proportions compared to even 10 year old digital process sizes..
If canon has made the jump to combining their sensor and ADC processes, then all chips will benefit, we just have to wait for the technology to trickle down.
full frame sensors use 20 year old fab technology.
not to mention that canon has litho equipment down to I believe around 90nm, and even if they wanted to go real high tech - nano technologies down to 2nm(!!)
but in reality canon's second fab already had a 180nm line. which is "leading bleeding edge" for full frame sensors.
the holdup wasn't the factory. the holdup was the patents.
canon got approved a crapton of sensor patents dealing with ADC over the last year. and they obviously feel comfortable with it because that 250MP sensor they developed was using on sensor ADC.
