With the 24-30fps output for 4k images, that moves into the territory of cameras like the Red One. On a basic level, that's what it's doing. Could the processors and sensors for these HDSLR cameras be hacked to give full resolution 4k images at a 24-30fps rate? I don't think they're there yet. If Canon is smart, they're looking into it because they could have a rabid group of filmmakers and videographers looking to get a Red-like camera for say $4000 (yeah, wishful thinking, I'm sure) - compatible with say XL mount or EF/EF-S lenses.
