It is a 64 page long report but plots 12 and\or 54 sort of iconically summarizes it: It is R^2 although R^2 sits  too low... It is unconfortable. Is it? Unless some Sugra embedded scenario locates it ''better'' or justifies it ''better''. See posts in G+ by U Schreiber.  Unless in the end is ekpyrotic ie no B Modes and no inflation... I guess ESA/Planck  will travel up north to a certain Scandinavian city very soon... but not yet the theory-inflation propronent(s).
