I first noticed this was changed on the Wiki so I did some searching on Google and sure enough, it says here that A&O4 will come out on October 7, 2014 instead of September 23, 2014.
Well, I just hope they don't push this back anymore. I really want to see this movie soon since it looks like it will be the best sequel yet. link
(It keeps saying I need to "write a longer article" so I'm trying to make this as long as I can so it'll actually post this. It's getting annoying...)
Edit: Well, that worked, but I guess I'll have to keep this unrelated part of the مضمون here یا it won't let me post it.
