If Sasuke is a wanderer, how could Naruto ever fulfill his Promise of a Lifetime?
But again, when Naruto said he'll "bring him back" it can be interpreted explicitly to bring him back to Konoha; or it can also be interpreted implicitly to bring him back to the good side. I suppose, the former is more in line...
Naruto did say he could not confess to Sakura before he fulfilled his promise. so...
Anyways, someone brought a nice benchmark earlier with the significance of movie poster from other series (i.e. Inuyasha or Rurouni Kenshin). I tend to agree with the observation. That is, if Hinata is going to play a role in the movie, it'll probably more for conflict introduction/resolution for her side. I'm still stand firm with my guess since she's introduced --that somehow she'll be the catalyst to make NaruSaku canon. I'll keep my fingers crosssed.
I like the fact that regardless of the hoo-haa with the twitter, we got a detailed sketches of Naruto and Sakura side-by-side. Some more we have Naruto's sketch behind Sakura's for height comparison. I'm quite certain that these two will play as main cast throughout the movie (hopefully as much as they were in Road to Ninja). There's no point to promote them in details just to skip their importance.

"What? What are you saying?"
