Tobi stated it here It would seem their have been others that attained MS but Itachi stated this before but how many completed MS and gained EMS?

Currently Sasuke now knows how to use a complete Sasanoo which should make his Sasanoo even stronger. The final form of Sasanoo now has armor but as seem with his last Sasanoo a shoot from behind is its actually it weak point. In its previous state a FRS could penetrate Sasanoo in its weak spot. I'm sure a kyuubi+Sage mode FRS could end Sasanoo, if he doesn't have the mirror.
