Harry Potter 6 going for July '09

[The Skirata Clan]

exactly HP is already a successful series they won't sink now. but they were afraid to bring competition to the new series. twilight wouldn't have done as good as it did if Bond or Potter would have been close enough. therefore the film would have been consider a flop in box and it might have kill the series before it took off. i would have done the same in that position. you don't want HP or JB to loose money either.
