its gonna be interesting because IMAX / dolby / 4DX / etc screens are reserved well in advance by movie studios, and WB and Disney both have enough power to demand exclusive windows for 2-6 weeks. Right now both say they will play in IMAX but i dunno
this years shitty Jurassic Park movie didn't play in IMAX because F1 and Superman had reserved those slots months in advance and Jurassic was rushed to release in time for summer
