We seem to have an answer to the question that I asked a few months ago - Is Sarmat program in trouble? Yes, it is. Kommersant reports today that ejection tests of the missile have been postponed until at least the fourth quarter of 2017.

Theoretically, it is still possible that the missile will be ready by 2020 as the Rocket Forces planned. But that timeline assumed that the first missile would be delivered some time in 2015.
