The last time we had anything to report on Warner Bros' Harry Potter and the Half-Blood Prince, it was the decision by the studio to move the highly-anticipated sixth installment to next summer from its original release date in November. As disappointing as that may have been, fans who enjoyed the 17 minutes of IMAX 3-D sequences in Harry Potter and the Order of the Phoenix should be thrilled by the fact that there will be even more 3-D for the next installment.

Last month, during the IMAX Corporation's 2008 Q2 Earnings Report conference call, Rich Gelfond, the Co-Chairman and Co-CEO of the IMAX Corporation told shareholders, "we believe this film will include approximately 25 minutes in IMAX 3-D split between the opening sequence of the film and the finale."

It'll be almost ten months before we'll see which sequences exactly will be in 3-D, but who knows? Maybe we'll even see a bit of 3D Quidditch next time.

In the meantime, you can watch the teaser for the IMAX teaser trailer which played with The Dark Knight here.

Harry Potter and the Half-Blood Prince will open in IMAX and conventional theaters on July 17, 2009.
