Not familiar with Di2, but VERY familiar with Campy EPS, having done a V1 installation and later a V3 upgrade on the same bike. What do I hope to gain? Easier and faster shifting. I'm none to fond of the amount of motion required to actuate the mechanical shifter. And braided steel cables have their own little maintenance quirks I'd like to avoid.
