I dont see why Kishi wouldn't allow a straight up kiss. He di it with Sasuke and Naruto, why not show one between Sakura and Naruto.
I want him to go all Disney on me. Lol. But really, who knows. Konan and Yahiko got a kiss scene. Well almost. I hope the only visible kiss scene is Naruto and Sakura, because it will be very special and once in a lifetime. I wouldn't be surprise that's the case. If anything, we can only hope anime does it if he can't. I mean anime has been doing them.
