brainburst and I have been advocating against 2/3" and for a 16:9 four/thirds size sensor for a lot of reasons but particularly due to a lack of 2/3" lenses that a) are reasonably priced and b) actually could resolve 3K as ALL existing were designed for less than 2K - most much less. Some highend 16mm lenses would handle 3K, but there isn't much out there and a lot more expensive than SLR lenses.
This sensor would be half the size of S35, so cost savings and more DOF but not so much that you couldn't manage it either way (whether you want shallower than 2/3" or greater than S35 for documentary, low light etc.) It could use the same larger pixels as the S35 chips, so better sensitivy/noise capabilities. The big advantage is you have already existing very high quality four thirds lenses from Olympus, Leica, sigma, etc. with a stop faster for the zooms (F2 instead of F2.8) and all were designed for digital sensors vs. those for APS-C and FF slrs which are only recently being upgraded/optimized on certain models.
Frame rates are more a function of the number of pixels so that shouldn't change by just going to the same number of larger pixels on a larger chip base, and it shouldn't really change the custom processing chips they are probably making as (like say Canon's DIGIC chips) since those are probably designed to work across all of the sensor sizes.
I am hoping this is a possibility and some of the internal specs upgrades (like possibly a switch to four/thirds since it is actually just the same technology as the S35 chip with fewer pixels - same micron size and same or easier spacing) may not have to cause a delay because at this point a lot of the lead time is just doing final mechanical design with prototypes to make sure all connectors are in the right place and all of those modules fit together, then ordering all of the parts, connectors (minor changes in the exact type of LEMO needed, not necessarily number of pins but orientation or mounting type or whatever, can add months to the delivery time.) Not to mention getting factory up to speed on final designs, because on these cameras - with much higher anticipated volume, tighter mechanics and probably custom chips, you have to get it perfect before you say GO. You can't go back and make circuit or mechanical changes like you could with the larger, looser, and lower volume REDONE.
If you want to read the entire discussion on four/thirds vs. 2/3" look at my other posts or brainburst's.
Michael,
I was first suggesting to RED 4/3 lenses a long ago,
Also to join Leica Cinema GmbH in Zürich to develop set of fast aspherical cine S35mm lenses.
That with existing Mysterium sensor development would make RED project a real competitive in both main markets:
HIGH = professionals
and
LOW = consumers.
