The placeholder showtimes on Smithsonian’s ticketing page has it listed as 3D for both Air & Space Museums (downtown DC and Udvar-Hazy in Chantilly, VA). This makes sense since both have converted to the laser system (which makes showing full-sized Imax 3D infinitely cheaper) and also since Lucasfilm didn’t show TFA in 2D at any laser locations last year.
Then again, Fantastic Beasts was also listed in advance on their site as being the 3D version but they’d changed it to 2D by the time opening day rolled around. Maybe something similar will happen with Rogue One, but I’m not holding my breath. Those of you who can see it in 15/70 are truly lucky.
My best friend from high school has had his heart set on getting a group together to see this at Udvar ever since early last month (Vader’s return to the big screen is a really big deal to him). If it does in fact end up being the 3D version, I’m positive my plea to not see it that way will mean nothing. My friend has perfect vision and also doesn’t care whether or not a movie was shot in stereo, so those are two things I got going against me. On the other hand, I’m way way way overdue for a new prescription. Maybe I can get contacts (I’ve heard you do not want to be wearing prescription glasses with 6p 3D systems) and just “go with the flow.” At the very least, the shots that are mostly/entirely cgi should look spectacular in natively rendered stereo.
