That tree may not flower but I bet Madara is going to hot foot it over there and suck up all the chakra that it had grown with, thus creating either a) Perfect Madara or b) Shadow Jyuubi

Then the fight will be with Naruto as the Jyuubi Jinchuuriki and him becoming the SotSP 2 and thus Ultra Kage, head of the 5 Kage of all the shinobi villages.

Sasuke gets to be Hokage, thus acting as a regional head along with the other Kage's and realising the Uchiha dream of leading Konoha.

Or some BS like that.
