Weight: system more important than sensor size?

I think you are looking at different market segments here.

Both Canon and Nikon have a very American view of their camera ranges, the bigger the better. Even though you can make FF cameras and lenses a lot smaller than they are today, the producers at least seem to think that the market want big heavy gear. Perhaps to show off? (You can see the 1Dx is better than the 650D simply because it is twice the size... Sort of like American cars)

Olympus and Sony on the other hand are very Japaneese in their designs, going smaller is better, to the same extremes sometimes, designing cameras that are not good to hold because they have become too small, at least for western hands.
