I'm sure many people here have already seen the prototype Campy Record Electric system, it's been used at Paris-Roubaix and other races as a prototype for the past couple of years. Here are the European patent office applications for Shimano's new electric system.
Interestingly the control mechanism is supposed to go within the seatpost. The Campagnolo prototype has the battery and computer mounted in a rectangular block under the downtube water bottle cage.
