I loved the combo from both two man teams... Sasuke said he will bring his chakra to Naruto's level; it makes me wonder if Kishi has powered up his chakra reserves as well... I won't be surprised because he has EMS now but still Naruto has way more chakra because he has been in this battle straight from training with Killer Bee and since then he has made so many clones that helped regain the tide of the war, then he fought the Bijuus and Tobi (who later turned to Obito in the same fight and also got the Ten tails and he's now the new SO6P)... without diverging, Naruto's chakra reserves is amazing especially with Kurama.
However, ever since his Dad came to the battlefield, Kishimoto has just toned him down, he hasn't transformed nor even used his own speed. Last week I was sure that Naruto could have taken himself and Sasuke out of the reach of Obito but instead chose to touch his Dad to use the FTG.
I think Kishi will make Naruto master the FTG and also, now that Sasuke has seen Madara use the full standing susanoo, he will also do it; bearing in mind that he has EMS... it will become Juubi Vs Kurama and Susanoo.
What an epic battle to come!!!
