Yes. It's a tremendous amount of data to read off the sensor and write through the I/O. But, IMO, the empasis should be on the camera being a capture and recording device not a device for image processing. Processing can be down downstream on a device more suited to that job.That's a good point, just like with the 4K on their cinema cameras. It's the reason the 5D Mark III can record a variation of 3.5K RAW. There'd still be a big hurdle on the encoder they use and the sensor readout speed.
