Doesn´t anyonone actually believe it could be a classic sub jutsu? I mean, I know we ain´t gatting the pin pal´s top spot shot (stroke) AT First sight, at least give him the probability of planning his ways long ahead of his opponent, we did see Sasuke´s EMS on detail, meaning it might be at the current moment being used to do its stuff.
genjutsu is possible, yeah, I´m saying Sasuke used Tsukoyomi. I would like to say Izanagi or Izanami, however Sasuke losing an eye on a 1st strike sounds out of context :=)
