I don't seen NaruHina coming at up for awhile in this arc. Naruto is FAR too focused on Sasuke/Itachi right now. And if Kishi does
Hinata: Naruto, I love you!
Naruto: Really? Let's go out!
Hinata: yay!
kinda thing, I'll be pissed :| lol. I really am hoping Deidara doesn't die and same with Tobi. They both need to live and be comic relief for the rest of the series

it could go down that Deidara does try to go after Sasuke, Itachi intervenes. Deidara goes to Akatsuki and tries to get other members to counter, Akatsuki doesn't care, Deidara gets pissed and leaves and joins Konoha group for the soul purpose of revenge and then be comic relief

(and Tobi just tags around cause he's funny). Granted, that really is doubtful but another possibility. Not a great way, really.. but maybe not joining Konoha, just being his independant ya...
And I see Sasuke x Whore With Glasses (Karin) happening, Naruto x Sakura (come on.. it's a SHOUNEN manga after all

main hero and main heroine always go together), Ino x Sai (if he's not ghey), Temari x Shikamaru (dur

), and Hinata x Kiba (if anyone). But, ah well. Kishi said he really hasn't cared to focus on relationships as is.
I'm still hoping for Naruto being captured, rescue him and come in time to stop it from completing so Naruto doesn't die but now has more control over Kyuubi chakra or they come too late and Kakashi has to do the jutsu of Chiyo's to bring Naruto back (the sharingan was opened, it's not a bloodline ability, he copied it

). That'd be quite dramatic I say. But, again, as Skaw said.. there are TONS of possibilities and it's all up to how Kishi handles it.
