Sorry to chime in the "Epic only" discussion, but I'm still very interested in Scarlet Dragon pricing.
A $6000 upgrade for a $35,000 camera is very reasonable, it is 17% of the overall cost of the camera.
When you apply this to a $10,000 camera and also remember that Scarlet "dragonizing" should be more expensive due to a need to replace some additional components along with the sensor, it seems that the upgrade cost will be closer to $8,000-9,000, which is almost a 100% of the cost of the camera, which is almost like buying a second body.
Though I'm sure RED will find a way to make this right as they always do.
In some ways it's worse. If they just released a Scarlet-D for $10k I could probably sell my Scarlet body for $5k and it would cost $5k to upgrade if they were the same price. So I'm actually paying an additional $3k for the privilege of upgrading. Then again since that would be seriously screwing us over I assume Scarlet-Ds will sell for more than $16k new, just like RED-Ones cost an extra $6k new with MX to make it worth while.
