I believe I have read this before.
However my personal opinion on the matter is Naruto will kill Tobi and unseal all the tailed beasts. They will all have lost theyre jinchurriki thus have nowhere to go. From there they will all get sealed into Naruto because he will learn awesome sealing techniques due to being an Uzumaki. Not only this he will seal them all into himself individually so he will have all 8 tailed beasts (Hachibi will hopefully be alive) sealed within him but they will all retain theyre form and theyre amount of tails so Naruto will continue with Kurama and use the other tailed beasts as a boost in power when he needs it.
Like this Kishi wont upset his fans (Although he does often) about Naruto losing Kurama and all the other tailed beasts just disappearing.
