I am a little nervous about how Harry Potter 7 will turn out....?

I am a HUGE fan of the series and I have loved all the movies so far, with the exception of all the parts the directors screwed up, and I'm a little worried about how the 7th movies will be. The 6th movie was pretty good, but it missed ALOT of key elements for wrapping up the series, like the fact that Dumbledore told Harry absolutly nothing about Horcruxes other than that Voldemort had seven. He's going into the next one with no knowledge about how to kill Voldemort, and knowing movie directors, he will probably just magically figure everything out, which will make me really mad. I just wanted to know if there are any other HP fans with concerns about the 7th movies as well?
