[/quote]Sasuke will gain the Mangekyou Sharingan from making friends with Kabuto and killing him. Mangekyou Sharingan has three different techniques: Amaterasu, Tsukiyomi and possibly Susanoo since in Japanese mythology, Amaterasu, Tsukiyomi, and Susanoo were siblings. Susanoo is the slayer of the eight-headed serpent Orochi, most likely hinting at a future battle between Sasuke and Orochimaru.[/quote]

I heard Susanoo is a storm god, so if Itachi has Susanoo then wow he can control the weather!!!! =D
