Looking at Obioto's face in the final panel, it seems he was concentrating on something, Maybe Izanagi Rikudo Style? I have a feeling that the Joint combo attack by Naruto and Sasuke won't do the trick. I suspect that Minato's long winded Rasen Senkou Chourinbukou Sanshiki mabob No Jutsu is gonna be done before this all ends with Obito.
