Warner Brother's just announced that the upcoming films of Deathly Hallows will be in 3D. Can't wait to see that Battle for Hogwarts popping off all around me. Check out this article from the Hollywood Reporter
Early 3D-conversion tests on Warners’ remake of “Clash of the Titans” have gone so well that -- combined with boosted enthusiasm for 3D in the wake of the “Avatar” tsunami -- the Burbank studio has decided to release not only “Titans” but also the two-part “Harry Potter and the Deathly Hallows” in 3D.
Looks like Potter just said Avada Kedavra to the competition.
