Yea that's what he said. But you know Manga/Anime, they'll find a way to make that other half appear some day for Naruto to use because half just feels weak. (don't worry I don't read Mangas ;P, no spoilers here)
My memory sucks, but didn't Madara look for sharingan eyes? The same way you can "steal" eyes, I'm guessing he can put em on whatever body he uses. Anyway, it'd be quite dull if he used the same technique as Orochimaru, so I'm guessing the mask/vessel theory is as good as any.
But oh man! Am I so glad I endured all the stupid-ass fillers, those last 4 episodes made everything worth it. Those who quit, cussed and did the anti-conformist talk against Naruto don't know what they've just missed. That was beautifully done.
