Hmm. Kabuto and Sasuke are both at sannin level but they have no village and are rogue ninja so they can't be titled as sannin. However i do believe Sasuke could kick Kabuto's snake a** anyday. i do think that Sakura, Naruto, and Sasuke should be the next great sannin. They should be the ones that the generation after Knohamaru's generation idolizes as the great sannin.
blah blah blah... yesh sasuke does have the [stke] p**** [strke] sharingan but that doesnt mean he is going to win... i mean he had the sharingan when he sparred with/lost to rock lee... so -shrug- just bcuz you can see your oppenent's movements doesnt mean anything. :p cool
