No, no talking about the past or anything.
The movie will probaly be like this.
MOVIE START
1) Starts out with Team 7 completing a misson. Naruto is bitchin about how boring the mission was, and of course itches for a much harder mission. Sasuke will quietly agree with him. Sakura will be like no Naruto, but deep down inside she agrees with him.
2)There given a mission by the Third(hehe, he'll be dead to anime viewers for a few months by then) to travel to some country, blah blah.
3) They traveled to that country, and then blah blah someone captured or attack, blaha blah blah, we must rescue or defeat blah blah blah)
4) Then Ice Queen will be introduced(blah blah blah)
5) There will be a final battle, Naruto will save the day blah blah blah
6) And travel back to Konoha blah blah
MOVIE END

Hehe, I'm probaly only correct about some parts.
But I'm 100 percent sure there will be no talking about the past, and if there is, it will be really vague.
