Tobi might be SASUKEEEE!
Tobi/Sasuke might be from the future!
Based off of pure speculations, don't you think that the one person that Tobi would allow to see his face would be himself? Granted, it is loosely implied that Itachi saw Tobi's face as well (for how could the Amaterasu technique that he implanted into Sasuke's eyes have
known when to activate, had the original owner not seen Tobi's Face?
Then Upon close examination of Tobi's war-fan, we see the seal for Heaven's
Curse Mark on page 9 of issue 564. http://www.mangareader.net/naruto/564/9
In this image, we clearly see the seal for Heaven's Curse Mark, as given to Sasuke by Orochimaru, on Tobi's war-fan. I'd glanced over this image three times previously before it caught my attention, because I subliminally saw three tomoe and assumed that it was simply a rudimentary Sharingan that Kishimoto decided to waste no time on.
Given the fact that we have seen so little about Sasuke's new Eternal Mangekyo Sharingan abilities, it is safe to assume that he, indeed, has new abilities. Furthermore, given that space/time techniques can arise out of the Mangekyo Sharingan (e.g. Kakashi's Kamui), it is not beyond reason to assume that Sasuke may have developed such techniques.
Who knows guys! hehe
