As unofficially announced by Warner Bros, the producer of all the HP films, the entire HP film series will be re-released, with deleated or extended scenes included.
However, some sites are not over-excited by this fact. Some worry that the extended parts will not add much to the pre-existing films. Some compare the extended editions to the kind shown on ABC Family from time to time, featuring less then a quarter of an hour's extra footage.
Though either way, the releases of the extended films will appease the die-hard fans, such as myself, WB might be hard pressed to please the average film viewer, when the previous film version can be bought for only $9.99 at most stores.
At the present time, little details are known about these extended editions, so, for the present, it should be counted as a rumor until WB representatives confirm otherwise.
