I have found this on youtube and i see in the video Naruto is on ground and it seems Sakura and Kakashi think he is dead. than it goes through all the music and shows Madara(Tobi) with the new outfit on and his new eye! Rinnegan eye from Pein. and with him is Kabuto and his self that i guessed part of Orochimaru..and it lastly shows Sasuke standing up and his eye changes.?
can someone explain to me this video and how this is out when the fillers just ended..because this video looks promising!
Video: since i cannot post video on here go to youtube and copy/paste
