To me, what I think is so significant about this, besides them featuring a good chunk of SiT (my favorite album) and AtG in particular, is the fact that they have FINALLY dropped several of the overplayed songs that have appeared in (almost) every single setlist since first released. For instance, the ONLY song from NotB is The Prisoner - not the title track, RttH or HBTN, nor 2MtM or Sanctuary - how freakin' awesome is that? Yes, FotD, IM and The Trooper are still there, but I wouldn't expect them to drop every fan favorite.
So I hope this sets a precedent for Maiden setlists going forward: include a few old favorites (and change them up!), but dig out many more of the great treasures deep in the heart of their catalog. Not sure if I'll manage to see them next year, but if not, I certainly hope there will be a live album from this tour, which I'll be first in line to pick up.
