The reason to believe that spoiler is fake is because 632 will be a team seven moment NOT team seven+Hinata moment. Maybe some Kakashi and Obito but most likely team seven ready to fight the Jiuubi.
If i remember correctly, this is the story of team 7, not team 7 plus Hinata. Sounds to me like some people are still thinking Hinata is tied to the eye of the moon plan, the ten tails is about to go into its final form, the allaince will be helpless then they think Hinata will somehow pull out a new Byuakugan to save everyone right?
No when the final form emerges, its going to basically be those set up to fight right now and then one of these happens:
-The rinnegan awakens within Naruto and gives him the power to subue the ten tails
-The tailed beasts awaken within the ten tails by Naruto calling their names, their individual beings take hold and weaken the beast from within, possibly freeing themselves and retaining their individuality, the tailed beasts are free and in one fell move, work with Naruto plus bee to use their power to do something extraordinary to defeat the ten tails. Me thinks this will involve the other 7 taking new forms, unless Kurama and Gyuki also work in this to which Naruto and Bee at least live.
