I think the market for smooth polished aluminium components was drying up for quite a while before C decided to go CAD futuristic carbon/plastic matt black, er, a bit like Sram?
They were quite slow to adapt last time, c1990, and no doubt their new products looked awful to the lovers of the previous design era.
I would say Shimano adapt more frequently but in smaller steps - campagnolo seem more settled and traditional, until a sudden necessary leap into the present.
