No, he ripped the mask of, but next week we will only see Madara or Sasuke and not the big reveal! Kishi will save it for chapter 600.. 
There will be a mask behind his mask.. ^_^, I'm curious as well though.This whole series was Genjutsu.
But I can't wait to find out who it is. I don't care about world peace. As long as I know who Tobi is I can be happy.
Just the fact that Obito was introduced in detail to us right before Shippuuden, and has been a character since the beginning of part 1 (Kakashi talking about Rin & Obito by gravestone, speaking to Sasuke about saving his friends) and also all the other stuff as being an Uchiha, Kakashi got the Mangekyou, had a "reverse Kamui" ability, Tobi had an Obito "good boy" personality, Tobi replacing his gooey arm with Zetsu (the body side that was crushed).. There are so many more things that when you add them up, made Obito quite a good candidate... but still there were some timeline problems.
I for one am really interested in how Obito became Tobi. It's funny as Obito was the Naruto of the Uchiha, and he turned out to be the exact opposite of what Naruto has become. Madara and Rin are definitely involved!
