Maybe the 9 tailed fox is gonna come out or those sage frogs use their jutsu to free naruto ( OR maybe Mighty Guy and his team will come and free naruto YOU NEVER KNOW...?? ) Remember when you saw konoha was attacked and you saw guy's team that they were coming back to the city its possible that guy and rock lee opens up their 5-6 gates and help naruto out
But i think the ma and pa Frog will help him out with their jutsu but you never know about guy and his team
