Due out this christmas
Last movie will be out 2010 I think they only get a short break after filming and possibly will start back up in the fall for the last one. Also I hear in Florida(USA) they are going to actually make a Harry Potter theme. There will be a hogwarts and also everyone will get to learn spells just like the movie. I think the theme park will be done in 2010 but I am not certain. JK Rowling of course will credit for it i'm sure.
