I have seen a lot of people talk about Naruto probably combining the two modes together. I think it is obvious to say he does cause he's already done it before. In episode 169 when Pain shoots him with a chakra rod in Konan's tree jutsu, Naruto combines both modes to override Pain's control. Konan then goes on to say "How is he resisting Pain's control at such a close distant?" You can clearly see Naruto with Rectangular Sage eye pupils and the fFox's orange slit eyes at the same time. I also have a theory on Naruto's Sage mode. Naruto now has 2 chakras, so I think the same way he was using the Fox's chakra and arms to help form the tailed beast bomb, he can use it to fight while he uses his own body to gather nature energy for sage mode, or vise versa. This way Naruto would be able to stay in perpetual Sage mode and maybe even use the incoming Sage Chakra to equalize the Chakra the Nine-Tails tries to steal from him when he enters Jinchuricki mode. Also can't wait to see a rasen shuriken while in combination mode. Maybe that's the Hurricane attack? The tailed beast bomb is essentially a rasengan in fox mode, can't wait to see the combo mode rasen shuriken.
