I would actually be a bit disappointed if those spoilers were true, though they sound legit (matching up with the bits and pieces we've gotten before). From the sounds of it, Sakura won't be interacting with Naruto's parents, and likewise, Naruto won't be interacting with Sakura's parents. And at the end, Sakura throwing herself crying at her parents, as she now knows what its like to be without them sounds like a really touching scene, but then Naruto just goes with Iruka -- no bonding or comforting between him and Sakura
at all about what they just went through? *sigh*
But then, that summary was just that, and made it seem like there isn't much interaction between Naruto and Sakura after meeting Hinata, when we know for certain that they have the discussion on the Hokage Mountain and by the fence where Sakura asks if this world is happy for Naruto, so it could just be that the spoiler was missing a lot of the things the person posting the spoilers didn't feel to be significant.
Only time will tell, and this movie still does have a lot of nice bonding going on between Naruto and Sakura regardless it seems.

Well I feared as much. It seems like Kishi really wanted to cram as much as he could into this movie.
- First of all there's the AU personalities and all the undoubtedly wacky interactions that will follow, like Hinata being a yandere and Sasuke being a playboy.
- There is the Akatsuki and what exactly their role in Tobi's plan is.
- There is Minato and Kushina, which also ties into Naruto experiencing what it's like to have a family. Something that will probably take up a good portion of the movie's plot.
- There is AU Naruto aka. Menma (There might even be an AU Sakura?) and then there are the four celestial beasts.
- Lastly there is the whole thing about Naruto and Sakura becoming closer and learning to understand each other better.
All in all, that's a lot to fit into a 90 minute movie, because unless I'm completely mistaken, all the previous Naruto movies have only been 90 minutes. Still, I have faith that Kishi and Pierrot can somehow make it work. However, based on what has been said in interviews and such, I think that escaping the genjutsu and Naruto's interaction with his parents will have the highest priority out of all these different subplots. I could be wrong of course, since this i all just speculation on my part.
The spoilers seem legit enough for me. I'm happy that part of the movie was to make Sakura understand Naruto a little more. It goes to show that Kishi really loves the bond those two share.
Still, I hope we get more details on some of the scenes. I want to know if after Naruto and Sakura are released from the genjutsu they just go their separate ways (Naruto to Iruka and Sakura to her parents). I think it would be more appropriate for them to have a little bonding time post-genjutsu, specially considering all they went through in there. It doesn't have to be Sakura inviting Naruto for dinner (although that might've been the perfect ending), just a little quick chat with Sakura asking Naruto how he feels now that they're back.
Also, what was the resolution with Sakura and AU Sasuke? I was never expecting something big, just a little thing that lasted half a minute would be fine. I hate to think that she remained lovestruck with him all throughout the movie. C'mon Kishi, Sakura is better than that.
Yeah, I just hope that Sakura's revelation will be done tastefully and not just as some sort of guilt trip. A little guilt will of course be inevitable, but as long as it's tastefully done, I dont mind. As for Sasuke, well I really truly believe that Sakura will eventually come to realize that her immature love for Sasuke is bad and so by the end of the movie, she will have moved one step closer to finally resolving her feelings for Sasuke, unless of course, this movie takes place before the Kage summit arc.
Even if we don't get a whole lot of Naruto/Sakura bonding, it seems like we still get something and I have a feeling that Kishi won't let us down.

Still, I agree with you and Paptala that a little post genjutsu bonding between Naruto and Sakura would be great.
And lastly, if that scene with Sakura hugging her parents turns out to be true...
