Staying with full length non-charity public gigs, Vancouver could have 14 live debuts(15 if they do Ordinary Love.)
I'm including EBW in those 15 since 99% of fans will be seeing these songs for the first time in person.
OK, I'll play along here. The only SOI song that has been confirmed as NOT being rehearsed, at least to the end of last week, is The Troubles. So, since no SOI song has been played before at a full length gig (except EBW, which you're including in your count), that could account for up to 10 of the 14 songs. Invisible has also been rehearsed, taking us to potentially 11.
That leaves another three, minimum. I suppose The Crystal Ballroom could be one, but that's still at least two old songs you're suggesting may be played live for the first(-ish) time ever.
You said nine songs have been done from the U2Request top 11-100 (with nothing yet from 1-10). I only counted five based on what's been explicitly confirmed so far, but I'm tired so my count may be bad - or that means there are up to four songs you're keeping quiet for now. Some of those four may be live debuts. They may not be.
I've been fairly confident in my prediction that A Man and a Woman will be played this tour, and it's on the U2Request list and has only been played once live, at a charity event, so it may be one of the 14.
Other songs from the U2Request list never played live before (by U2FP's criteria, so only counting full length shows): Acrobat (which doesn't count for this guessing game, since it was #1), Heartland (likewise, #9), Red Hill Mining Town, Lady With the Spinning Head, Drowning Man, Love Comes Tumbling, Invisible, The Crystal Ballroom, When I Look at the World, Promenade, Luminous Times, The Wanderer, Ordinary Love, Hallelujah Here She Comes, Salome, North and South of the River, Fez-Being Born, Some Days are Better than Others, Iris, and some drug-addled people even wanted Stand Up Comedy to makes its live debut.
That's a wide pool. Invisible, The Crystal Ballroom, Iris, and Ordinary Love are already accounted for above. So to get back to guessing the minimum two old songs, well, almost all of those would be massive surprises, and of course a live debut could be drawn from beyond this pool too.
I'm too tired. I'm out. Somebody else keep going, or show me something I've missed/where I've made a mistake.
U2FP, you're probably having a right laugh at this.
