You don't think simultaneous rather than consecutive bracketing matters? I guess it wouldn't, if subjects were all perfectly still and cooperative, but that's hardly what real life is like. Giving a greater effective depth of field for a single shot is pretty cool IMO. It would be even cooler if they'd address over/under exposure to do single-shot HDR at the same time, but maybe they're saving that for v2.
Obviously I have no idea how they've implemented this camera but right off the top I can see several advantages to being able to have multiple sensors firing at one time. The first obvious advantage is HDR photography, where each sensor would use a different setting, then software would combine the images, using different settings for different lighting areas in the picture. Similarly, this same tactic could be used for different focal ranges and depths of field. Personally, I'm just happy to see that someone is trying to rethink what a camera is. Other than being digital, cameras haven't changed much in how they fundamentally work in many years.
