Juubito goes for Naruto. I doubt Naruto would have died that fast hes really really fast. He could have probably dodged it so saying Sasuke "saved" him isn't right. Maybe Sasuke instead wanted to Solo Juubito instead of Naruto fighting.
Also him saying,"not you". "I will be the one to delete the past". If he was gonna delete the past shouldn't the images of Kakashi and Sakura be marked out also? Maybe he wants to delete the past as him erasing some of his mistakes and he wants to defeat Juubito, so he can "erase" the past and Naruto being crossed out means he doesn't want him or him doing it.
Eh, just an idea, but it still probably means he wants to FHK NARUTO.
