Personally, I think not having
any deep cuts (depending on where we draw that line) is, kind of, a bit less likely than the set having 1-3 deep cuts. Again, it probably depends on what we consider as deep cuts, but even if they go with a very standard and stale setlist approach, it would still have room for 1-2 more theatrical set centerpieces and I think it'd be more odd for them to
not explore early catalogue outside the most obvious cuts than to tour the world for two years with a set that has almost nothing refreshing from their perspective.
Again, I'm not expecting them to play Still Life, Infinite Dreams, Killers, No Prayer for the Dying, Judas be My Guide and Seventh Son of a Seventh Son in a row, but I also doubt that they'd roll with a set without one or two songs of more "surprising/deep cut/etc." nature. Moreover, Nicko's situation might even add up to the possibility of some such songs being played, as they could technically be lifted to the table as "substitutes" to other songs they might consider in the first place.
Perhaps I'm being overly optimistic or something, but I've noticed that there hasn't been a "worst case scenario" sets for a long time and whenever people have predicted them due to the band being too lazy to rehearse this or that, or feeling obligated to play X amount of hits, their setlist have
usually included at least that one or two pleasant surprises or otherwise thrilling inclusions and for all we know, it could very well be so for next year as well.
Like, even if you just lay out all, or most of the 80's hit singles and other obvious tracks, it still leaves room for a deep cut and a epic show centerpiece, such as Rime or Seventh Son, so I think that even the very worst case scenario wouldn't be absolutely disastrous. Playing mostly singles, Phantom, FOTD and Hallowed sounds a bit too rocker-heavy and stagnant for a Maiden set, especially after the brilliance of TBOS-LOTB-Future Past, so I just don't think they'd
totally drop the ball now.
...which is not to say that the 2025-26 setlist wouldn't be very heavy with obvious classics - of course it will be. But my guess is that it won't be
quite as grim as some believe it'll be.
Well, we shall see! (no shit)
