I was reviewing this question and it seems to me that this meta question should apply, and that the question would be off-topic as too localized. However, when trying to flag it as such, I found that the too localized close reason no longer exists - does this indicate that release date questions are now on-topic for the site, and if not, how should they be appropriately flagged?
(I should note that as originally written, the main answerable "question" I could see was whether a sequel will be coming out - if that is not retained, the overall question of release dates remains.)
