I'm really excited about the film(s). I pretty much loved every film of this franchise since Order of Phoenix. And the preview for the final film(s) is so well executed, and just so very awesome.
So, first part in November this year and second part in July 2011.
This is going to be awesome.
ETA: I should state that I stopped reading the series post Order of Phoenix. The books just became too unwieldy for my taste.
