Quote from Deva
At this point it's more or less unpredictable, we just don't know enough... but I would be really surprised if Naruto survives.
Of course Naruto will survive... this is from a mangaka who resurrected Kakashi, Shizune and the old frog dude after Konoha was destroyed. I pretty much lost faith in Kishimoto's capability for profundity after that. I seriously doubt he'd off his title character, I'd be more surprised if he had the balls to kill Naruto off.
