According to this thread: http://www.shootfortheedit.com/forums/viewtopic.php?t=1916&sid=92a1e33e683b512945d3917615cda79a on Bay's blog, and the two other articles linked in there. Shame, I think. I really, really enjoyed Matrix Revolutions and 300 on the IMAX. Hell, seeing it on the bigger screen was really the only thing I enjoyed about the former. And TF seemed like the perfect kinda movie for IMAX screenings.
