Honestly to some degree its hard to know that the previous generation and those who died to install the future of hope all come back to be the reason they survive.
Part of me wants to see the epicosity of the Hokage, and yet part of me wants to see the future generation do the fighting.
But I kinda agree; however, I'm guessing Naruto and Sasuke will face the Juubi (symbolically the older and younger son facing their father's enemy...and finally working together). Also, Sasuke seemed intent on killing the Bijuu or whatever.
I can't see Sakura taking Obito on, AMD so I think she among others will face Madara....because his attacks are devastating; however, they don't completely annihilate you...meaning she'd survive the attack.
