Oh that is what you were referring to. They did put up a barrier around the Juubi, Naruto and the others are inside of it. Hence the tinted sky in the background.
Rushed, the war started about 120 chapters ago. This battle feels like it has been going on for nearly as long. Remember when it was Naruto and B vs Obito and the revived jinchuuriki. Then Gai and Kakashi arrived, then Madara arrived, then the rest of the shinobi army arrived, then the kages arrived. Not to mention the numerous extended flashbacks through out this entire thing. Pacing problems are the author's fault. You can't excuse the nonsense that has been going on as some horrible attempt to maintain pacing, when the lack of pacing is the author's fault in the first place.
Uh this entire little thing was pointless and stupid. First we are to believe that the 4 hokage are strong enough to erect a barrier that can contain the juubi when a short time ago. Naruto tried to measure the Juubi's power, the kyuubi told him it was pointless because he could only measure that it was immeasurable . Apparently immeasurable power < the four hokages. As far as Naruto's and Sasuke's attack, a poor attempt to create suspense. What is amaterasu going to do against the Juubi exactly and Naruto's Rasenshuriken couldn't even hurt the third raikage.
See this series prior to the time skip particularly the chuunin exam, for handling multiple plot points and battles at once. There is not actually so much going on and if doing so much at once is beyond his ability he should not attempt it. There is absolutely nothing wrong with finishing up a particular plot point before moving on to another one. Large scale battles are hard to write and keeping track of multiple plot points is not something this series has been good at. Hell Naruto can't even maintain continuity.
Uh Madara just not going there. Obito leaving to go reminisce with Kakashi. Well at least we know they have to somehow convince Obito to swtich sides. I don't see how the Juubi can be defeated other than by separating it back into the individual tailed beasts which is what the sage of the six paths did and only Obito can do that. Either that or Obito or Madara will finally decide to just move forward with their plan and become its jinchuuriki, or worse yet Naruto could. Uh
