Ok, maybe I'm just crazy or really overanalyzing or something but hear me out.
You know how the new crappy opening for the Naruto filler starts with all the people leaving the house, then the title "Naruto" as the characters are looking at the sun?
Well, if Pause it just before they cut away from that scene to Naruto looking all serious/depressed against a red background you'll notice there is another person who comes into the camera's path for just a split second before they cut away. All you can see of that person is their leg and hip.
I think it is Sasuke. The position of the equipment bag, the pattern of the bandage wrappings and the shorts, it HAS to be Sasuke!
Pause it right around 00:13 seconds into a Dattebayo file and you'll see what I'm talking about!
Does this mean to imply that Sasuke will eventually come back as a good guy?
