If the format is well thought out - and Adobe is in a good position to make a good judgment about all kinds of different scenarios - then it is entirely possible to accommodate any sensor each with its own characteristic, technology, patterns, custom processing, etc. The reason Capture One and other SW packages need separate support is because each manufacturer uses a different format. You need a module that translates that format. But if you have a universal format that can accommodate a very wide range of sensors you will not need all these different modules anymore. > To exemplify, the FOVEON sensor, is *radically* > different from the Canon sensor.

As stated above, if the format is well thought out you can accommodate all these different kind of sensors with their specific properties. I have not studied the DNG format of Adobe so I am not sure if this is really what they are after. Nevertheless, it is entirely possible to accommodate all kinds of sensors including the revolutionary Foveon concept (which really hasn't taken off to not all that much surprise...)
