That's my thoughts but you do know it's going to be something really stupid like he uses the mazu statue thing or whatever it is and kind of instantly absorbs the juubi! And being the host will make him very IMBA it will make edo tensei look like crap. But you know what I'm kind of hoping it does go that route. Because if he is able to beat back everyone and naturally absorb the Juubi with a living body than I am calling BIG BS! In all honesty I think a combination of Hashiarma and Minato can beat him if he is alive again. Forget everyone else! But eventually Sasuke is going to be an enemy again I don't see him staying good. Even more so with the foreshadowing of him still being bad or twisted. Wanting to kill the tailed beasts outright. Naruto won't stand for that so Sasuke will have to change his ways! But Sasuke won't change his mind. And he's an uchiha so he will see Naruto wanting to save the tailed beasts as betray to Konoha and than he will want to kill Naruto to defend and protect Konoha. This will make every ninja in the alliance really angry and than Sasuke will think everyone wishes to betray Konoha and he will want to crush everyone and start a new konoha free of betrayal!
I'm just trying to put myself into Kishimotos mind and this is the only logical or unlogical outcome I can see. Watch something like it will happen! lol
