Dark Knight's IMAX sequences on Blu-ray

From Engadget

Enjoying the small clip of IMAX The Dark Knight footage featured on the recent Batman Begins Blu-ray release? Even before the next flick hits theaters, director Christopher Nolan has already revealed plans to convert all the scenes shot for IMAX screens for use on the Blu-ray copy, whenever it hits shelves. Some cropping will be done to make everything fit but we'll still enjoy the extra detail in 1080p.
