I'd say The Alien, Invisible Monster, Awaken the Master and the title track are practically certain in the set list.
Sleeping Giant won as best song of the year in the Prog Report pool and James is really into the song, it might have chances. After releasing the video so close like this to the tour, I think Transcending Time also got big chances.
Following my logic, only Answering the Call is missing, would really be unfortunate like the guys have said, it is the best song on the album for me. But I don't think they would play like aaaalmost the whole album, missing only one song. Maybe they will play the entire album, or either SG or TT will not appear on the set, or they'll swap a few songs from night to night.
Anyway, can't wait to see how this set list will be like!
