aspect ratios - 4:3 vs 3:2

Just curious. Does anyone else think new cameras should be 3:2 instead of 4:3? I speculate most image viewing these days is done on computer & TV screens, not prints. I don't remember the last time I saw a new laptop or large-desktop monitor, or new TV that was 4:3. IMO, 3:2 images "fill" 16:9 screens pretty well, but 4:3 images waste too much space on the sides. Sure, 4:3 cameras can be set to create 3:2 images, but most do so by cropping, at which point you're wasting the lens' angle of view and (more trivially) losing pixel count.

Im curious what others think.
