The only thing that might cause a change back to the original release date is some toy manufacturer/retailer getting absolutely medieval on WB's asses but that is so unlikely, both because of the licensing contracts with WB that probably let them do pretty much whatever they like, and because of the length of time it would take to bring something like that to court.
It's a done deal, accept it, move on.
