I suspect that electronic viewfinders will end up almost everywhere and will be better than optical ones (eventually)? I think we should be prepared or expect radical change in cameras and, perhaps as important, the software that will run them. At some point, the software will analyze a scene the way we do (or in that direction) and turn it into not a two dimensional bunch of pixels but break it down into its components (Uncle Fred, the pine tree, some grass, Bob's car...). Depth of field may end up being a variable we can adjust like colour.
Ten years...twenty years?
