Something else that should be considered is the possible deaths of the remaining Konoha 11, including Hinata.
Tsunade and Co. didn't become Sannin until their entire platoon died and if history repeats itself this may come to pass for Team 7 to become Sannin. ALL the rookies just charged in as a group.
Hmm, good observation.
And maybe it's here where Sakura's gonna surpass Tsunade and she'll bring them all to life, IF she has both Yin and Yang chakra stored.
But I think I might dream too mcuh tho'...that's what the Sage of Six Paths and Nagato did... tho' there's a liiitle something that might connect her to them, so to speak.
