This time around, I'd actually lean towards thinking there will be one or two significant changes to the set list, because they've been known to do that on the redundant legs of their cabaret tours.
But I'm not expecting anything mind boggling. On this sort of leg, they tend to forget about the original tour concept. I honestly wouldn't be surprised if they played Wrathchild and Phantom instead of Where Eagles Dare and Greater Good, for instance. I doubt they would go for another deep cut or play a new song.
