May 31st was the last day DS played in the IMAX theater where I saw it. However, the two other IMAX theaters where it was playing in my vicinity (well, between 30 and 40 miles away) are still showing it - and they're both still showing it four times a day. So, yes, it's still possible to see DS in IMAX in some parts of the country if you're willing to track it down and drive a bit farther than you might otherwise. Though as far as I'm concerned, seeing DS in IMAX was well worth it.
In fact, I'd love to see DS in IMAX again, but I don't know if I'm going to be able to find the time.
And thanks for the link to that Friday estimate, jimbo.
