I don’t know what crawl a screening would have, but I can’t imagine an official blu-ray release that doesn’t include both. Releasing the unaltered cuts at all blows the idea that Disney would want to impose one particular official version to hell, and putting them both on there with seamless branching is just too easy to not do, especially since there’s such a difference of opinion about the issue. I think the only real question is whether they use the proper '81 for the ANH crawl or the one from the SE.
