Im gonna wait till Sony announce their thing
I'm not pushing RED or Sony because I own both, paid normal price for both, so I really don't have a dog in this hunt.
Still, it seems to me that Sony lumps their cameras into a series of price points and intentional upgrade cycles.
Either a fs100, (inexpensive), fs700 (medium inexpensive), F3 (almost expensive), srw, (very expensive) and since they have this and their eng territory to protect, they probably will always hobble their less expensive cameras like the F3 on down.
Not that RED doesn't do some of that with the Epic and Scarlet, given the fact their virtually the same cameras, minus the processing power to go to higher frame rates without cropping, but overall unless you must have higher frame rates, there is little difference between the two cameras given the fact you can buy 3 Scarlets for the price of an Epic.
Anyway I think that since you work with limited crew, having a real raw file, would go a long way to freeing up your on set workflow.
It's probably worth renting one and trying it.
And BTW: RED has Ridley Scott endorsing their cameras. I don't think Ridley is doing it for the free rental.*
*But then again Ridley is also a producer so maybe he is doing it for the free rental. (insert smiley face here, because nobody wants to make Mr. Scott angry).
