I would say Rime's return is a no brainer. I don't see any particular reason to bring back SSOASS to be honest, but Bruce expressing interest in it publicly makes me think that it has a decent chance. I wouldn't surprised if both Rime and SSOASS end up in the set, especially with the band leaning heavily into pretty short/uptempo songs. The trio of Rime/SSOASS/Infinite Dreams is probably enough to satisfy the proggy side while the rest of the set would be hits/uptempo oriented. I expect Phantom, Hallowed, Fear of the Dark as well of course, but I think that's it for songs above 6 minutes.
Ironically, including both Seventh Son and Rime would have been a good way to give Nicko some rest during the show.
