The competition heats up? The Russians have delayed until late 2016 the first test flight of the heavy-lift version of their new Angara rocket so that they can fly it with its own new upper stage, rather than using the trouble-plagued Briz upper stage used on Proton.

In other words, they want to dump all the components of the Proton as soon as possible. Whether this will solve the quality control problems that seem to be systemic to their aerospace industry however remains questionable. If I was a commercial satellite company I would have as little faith in Angara, until it has proven itself through a number of launches.
