It seems that it is indeed the EMS that was spoke of.. as both of them have straightened tomoe due to the combined designs.. and transferring the eyes awakens the EMS. But then again.. they were the only two who had the EMS.. so it has to be Izuna and Itachi's Mangekyo's it is talking about since Madara's is not straight tomoe, and neither was Sasuke's. Meaning Madara was talking about the transferred Mangekyo eyes.
