Seems to me if you can make a slick looking trailer like that, it’s not a huge stretch to include all the footage for a DVD/BR release. I mean, they must have recorded all the songs to make the trailer.
I hope if they do record a live album for CD/DVD/BD release, they wait until they do another leg of shows and change up the setlist a bit so they could possibly include ALL of the songs played on the tour legs. Ideally, it'd be neat to see them play all 7 songs from AVFTTOTW and include them on a live release.
So far the current setlist runs about 105 minutes long, while the previous live album,
Distant Memories, runs about 150 minutes long. I mean I wouldn't mind a short live album, a nice 2CD/1BD set could be neat, but I'd love to see them do what Rush did with their Snakes & Arrows Tour - do a second set of shows with swapped out songs, and add those to the first tour legs and make a longer album.
I also just want to hear them do every new song love.
