New Planck 2015 data still strongly favors Starobinsky inflation. The full results of the Planck experiment as of 2015 are to appear on the arXiv server tomorrow, but the pdf-s are already available for download on the Planck site [1].

I have just checked my reading of the data with an expert working on this and he confirms: The Starobinsky model of cosmic inflation [2] is still (as it was after the Planck 2013 data) the model with the highest Bayesian evidence as it is right in the center of the likelihood peak of the Planck data and at the same time has the lowest number of free parameters.

Everybody: forget those tensor modes for a second. There is something much more interesting going on, and as opposed to tensor modes which may or may not have made an ever so faint appearance, it is real, observed, tangible, unmistakeable physics. With highly interesting theoretical implications.
