"SRAM is developing an electronic road drivetrain, and based on US Patent Office documents BikeRadar acquired and examinations of a prototype group at the Amgen Tour of California, we are confident that it will be a fully wireless system that could weigh less than the wired electronic drivetrains from Shimano and Campagnolo. It appears the new group will also usher in a new type of shifting — a button on the left lever will move the rear derailleur one way and a button on the right lever will move it the other way; pressing both will shift the front derailleur.
