Yes. It will be what the original aspect ratio is. I only wrote 2.39 because that's what the press release says the digital version is. I don't think there is any reason to believe that Disney will screw up this release. They absolutely screwed up the movie itself, but the disc should be fine.
Well...I've got to admit that steelbooks looks very nice.
Unfortunately, the movie that it will hold is absolute garbage. This is the worst movie I saw last year. So I'll pass.
