Any info about pricing and availability?
At 12megapixels, the 9x11 inch version is quite interesting, although I feel that they could have gone up to at least 30~40 megapixels with a lower sensitivity.
My guess is that this device with 75 micron pixel pitch can be fabricated with the same equipment used to make LED screens, which now go to about 500ppi, so 50 micron pixel pitch. If so, the resolution of these relatively affordable large sensors will probate stay limited to what the larger market wants for phones and such. For example that 500ppi translates to 5000x4000 (20MP) in 10"x8" format, or 5500x4500 (25MP) for this idiosyncratic 11x9 format.
So for resolution, it could be limited to about what 1" format now offers, and under that resolution limit, I am skeptical that the virtues of large format lenses will be visible.
[UPDATE: I see now that phone screen go to 577ppi, so the resolution could get to about 5800x4600 (27MP) in 10"x8" and 6300x5200 (33MP) in 11"x9" -- or about 2900x2300 (7MP) in 5"x4" format, making it rather clear why they are not aiming at the far more widely used 5"x4" format, which would work with a far greater array of lenses and view cameras, and would offer distinctly less bulk and more portability.]
Dynamic range could potentially be stunning -- but for now it is limited by the 14-bit ADC, so no better than some entry-level DLSRs.
Users of extensive camera movements might have a good use for such a sensor.
