Wouldn't rule out a a WTF Barbie style surprise 10/6 or 10/27Ā and or IMAX re-issuing Dune Part I 10/27 (they arguably should have done a DUNE re-issue 9/22 ala Avatar instead of BARBIE)
Of course all this dependent on if DUNE stays where it is. I would imagine some of the LA/NY opening Killers will open it in Imax 10/6.
