2027 seems like the most likely candidate for when the Paris live album/video will be released, and I wouldn't be surprised if they're planning on going bigger with it after such a long break with a limited cinema release and whatnot. It wouldn't be entirely inappropriate for Maiden's last release to be a live album of what they likely consider their "ultimate" tour featuring some of their all-time strongest material, rather than studio album number 18. Plus it still wouldn't preclude future touring, but they wouldn't have to commit to a full-length album tour.
You think so? Their last album with only songs from before the reunion. The songs after that are irrelevant and can be ignored. I would find that totally inappropriate and a pity.
