I think Bruce might use a light sabre rather than Cyborg Eddie.
We should see the fight!
If they use a fusion of the 2 Eddies (like on the tour poster), it will only be for the big Eddie. It would be so cool, but I hope to be only Samurai Eddie (because this is still the new album tour and we must have it), although it would be strange to see it in a futuristic stage.
The walk-on Eddies will be 2 separate (like this year) - SIASL/Cyborg Eddie (appears during Stranger In A Strange Land, Heaven Can Wait like in '86 or Wasted Years) and Samurai Eddie (appears during the instrumental sections of The Time Machine, Writing On The Wall, Hell On Earth, Senjutsu ofc or why not for the empty middle part of Days Of Future Past).
Future - the futuristic stage set (plus some Japanese towers or Nicko's drum kit to represent Senjutsu), Senjutsu songs.
Past - the modern futuristic stage set (again, like in 1986), SIT songs.
There's no way they will use the shape of the stage from 1986. I think the new stage will be better.
