Alright, my thoughts:
The Final Experiment: I definitely expect Sail Away to Avalon to be there, and if they will play the set chronologically or at least start with the TFE intro, I can see The Awareness being played.
Actual Fantasy: I'm pretty sure it's going to be The Abbey of Synn and Computer Eyes. Arjen knows it's his least-popular album, so I suppose he'll just pick the tracks that are well-regarded.
ITEC: that's a tricky one. Valley of the Queens is a fan favourite, it's short and Anneke is there, so that's probably a given. I think that perhaps Amazing Flight might be in the set for Arjen's surprise appearance, and we'll definitely see more songs from it. I'd love to see Isis and Osiris with the lineup they've got, so I hope for that and not for Castle Hall, though I won't complain either way.
The Dream Sequencer: my bet here would be Druids and 2084.
Flight of the Migrator: Dawn of a Million Souls and Into the Black Hole, pretty sure about these two.
THE: they'll probably play some fan-favourites like Pain and Love, indeed. I don't really care about what gets played from this album because I've already seen it performed live.
01011001: This is the album I want to see at least four songs being played from.I would say one of Ride the Comet or Liquid Eternity is a must, given that Magali is on board. I mean, they can use Magali on other songs, if they wish. But, hey, I won't complain if they'll play both, I like both songs. Would also love to see Waking Dreams played, since both Jonas and Anneke are on board. I suppose Age of Shadows has a good chance of being played too. If they aren't going chronologically, perhaps The Sixth Extinction can close the set before the encore if there is one. I would love to see River of Time too. This is going to be fun.
TTOE: I'm tempted to say they'll go for a medley from the first Phase, but since Marco is here and he doesn't do a lot there, I suppose they either have a different plan or will use him on the other songs. I'm pretty sure The Theory of Everything Part I will be played, though.
The Source: no idea since I haven't heard the album yet, but again, I'm reasonably sure The Day that the World Breaks Down will be played as the first single from the record, and perhaps Everybody Dies will make it too, since Arjen said it's probably his favourite from the new album.
Star One: no idea, they can play basically anything. If I had to pick two songs from each album, I'd go with The Eye of Ra and Intergalactic Space Crusaders from the first, and Human See Human Do, 24 Hours from the second. Wouldn't mind seeing Master of Darkness, too.
Bottom line: Arjen has so much great material, it's so difficult to compose the setlist to satisfy everyone. Especially with 16 singers on board. Damn.
Also, I really hope I won't get spoiled on the setlist in advance. Especially at our meetup before the second show.
