i still believes that they'll be back anytime soon.. all 5 of them.. and I'm sure that they'll go all out since they now know how Madara fights and have idea with his jutsus.. Mei still hasn't shown the extent of her KKGs esp. her Boil Release, A still has to prove his worth as the Supreme Commander of the Allied Shinobi Forces, Gaara has more to show, Tsunade still has to a loophole of sage modes to fill as well as to give justice to her illustrious pedigree and Onoki must for the last time, collect the lost pieces of himself and defeat the one shinobi perfect for such feat.. they'll be back.. BELIEVE IT!!!
