They're stalling us again!
At least they gave us a little more information on what to expect. But now, it seems Tobi isn't some super old guy after all... He might very well be someone near Kakashi and Guy's age, or at least was around them. This might be the guy who got the news that Obito died on his mission, got really mad, and decided that the world wasn't worth the freedom it had. xD
Or better yet, saw Kakashi of the sharingan with his clan's doujutsu, got a little frustrated when he got beat by Kakashi, then decided to destroy the world after defection.
