Wrong on one thing Orochimaru did have sage power as he absorbed his senjutsu chakra from kabuto

http://www.mangahere.com/manga/naruto/v60/c593/21.html it clearly stated that it was Orochimaru's chakra so him being in possession of senjutsu chakra made him a sage.. just not a complete one.. it's the same as how Naruto became a perfect sage while Jiraiya only could do Hermit mode.

Oro was a sage just not a perfect one liek Naruto and Kabuto!
