or hadnt they come up with the plan at that time. but orochimaro knew akatsuki wanted naruto back in the forest of death, cos he had the chance to kill him and didnt cos it would cause trouble, my take on it anyway
There was originally 9 members. There is 8 members now that Orochimaru left.

9 members ---- 9 yoma. Sounds like everyone gets their own yoma. The details to Orochimaru leaving Akatsuki have not been revealed. It is possible that Oro had used the Akatsuki to get the snake yoma and then once he got what he wanted he betrayed them and left. When we see pictures of Oro when he was younger, he has the creepy eyes, but he doesn't look as snakelike as he does now.

The whole Orchimaro has a demon is a good theory but it just dosen't seem to pan out. If his Chakra really was out of the ordinary wouldn't someone have mentioned it by now? Plus why the hell would he need the sharingan if he had the powers of a demon to rely on for his jutsu.
Naruto has a demon also, but we already know that that is not enough. He still needs to develope, train, and learn new jutsus as well. Having the yoma makes them stronger, it doesn't make them invincible.

Its a very interesting theory and certainly makes a lot of sense. I wouldn't have thought of it on my own since I don't have any knowledge of japanese mythology (although I did hear of the story about Orochi and the sword) but now that I have heard it, I'm definately going to be paying closer attention to subtle hints that Kishi might be leaving us.
