Well, they seem to give us a few songs a tour now that have either never been played or haven't been played in a while (not counting new songs at the time):
VT tour: New World Man, Between Sun and Moon, Vital Signs, By-Tor and the Snow Dog, half of Cygnus X-1 (as opposed to just a tease at the end of YYZ) and Working Man
R30 tour: Between the Wheels, Mystic Rhythms and Xanadu
S&A tour: Digital Man, Entre Nous, Mission, Circumstances, Ghost of a Chance, Witch Hunt and A Passage to Bangkok
TM tour: Time Stand Still, Presto, Stick It Out, Faithless, Marathon and The Camera Eye
So, I think the odds are good that we see 3-4 songs that have either never been played or haven't been played in at least 10 years. The set list I posted has 6 such songs, although 3 of them were played on the VT tour 10 years ago.
With any luck, they decided to not play Jacob's Ladder last time out since they were saving it for the next tour.
