Considering that we have our villians.. Sasuke (depending on when he will turn/IF*), Orochimaru (same applies as Sasuke) Madara and Obito....
Team Current Kage have not shown up to the actual battle yet....though at this point all they can do is assist the Edo Kages...
Juugo isn't doing anything but watching Sasuke's resolve unravel. Team Hawk is roaming with Oro until he makes his entrance. Sarutobi is still recovering from the beyond blood line limit. Hashi is fighting Madara, while the Alliance watches. Bee has been MIA since Sasuke pretty much showed up.
Minato will finally reveal his talked about jutsu. Hopefully Kishi will show us some elemental/Affinity jutsu from the 4th so we can see what else he has besides variants of Rasengan and FTG combinations. Once Minato along side Tobirama fuel out their momentary worth Minato will give his side of the Kyuubi over to Naruto. At this point super power and speed is needed to even match Obito. We have seen Sasuke and Naruto fuse their techs together but we will see something on a bigger scale soon.
Madara will show off his combination attacks as well. Hashi will realize that Madara has the edge over him. Madara either consumes Hashi or somehow takes over his body....(he must have a back up plan for RT)
Depending on what Kishi wants to do with Oro he could have become a babyface and fight alongside the Kages...or he could have Oro body snatch Madara or even Hashi at this point. (though he needs Uchiha DNA)
With Naruto getting Kurama's full chakra reserve back his speed will be unmatched...though his power will still need an improvement to damage Obito. Finally after four wasted chapters building up to this moment..Naruto depletes his own chakra reserves and the bijuu power seeps out with him becoming the complete sage of the six paths. He will get a new cloak form or a completed form. One that rivals that of the look of Obito with a lighter look. I could go on..but i'll stop there
