Here's an interesting post I found on 2ch (credit goes to the nameless poster who made it):
It's a list of names of real life Ninja used in the manga
Sasuke -> Sarutobi Sasuke
Sandaime -> same one, obviously.
Sakon -> Yokotani Sakon
Tayuya -> Oiro Tayuya
Danzou -> Katou Danzou
Tenzou (Yamato's real name) -> Watanabe Tenzou
Kakuzu -> Zatou Kakuzu.
Konan -> Kanbeno Konan
Hanzou -> Hattori Hanzou Masanari.
The "Zou" in "Danzou" is spelled with the same character as the "Zou" in "Hanzou", but I doubt they're the same character...well, who knows. "Danzou's" "Dan" is actually the same "dan" in "Hidan."
"Zou", btw, is also in "Tenzou." (same kanji).
What's interesting is that Konan is apparently the name of an "actual" ninja.
Oh, and I'm leaning toward the Madara being in possession of Obito's body theory... :p ... not that it has anything to do with this chapter or the spoilers.
