Interesting! I was skeptical of the rumors of SiT, just because I didn't think they'd omit a Senjutsu tour, but doing both makes sense.
I, too, read 'Arry's statement to mean that they're not going to repeat the first three songs. So I think from Senjutsu we definitely see Hell on Earth, very likely Days of Future Past, and hopefully two of the other three 'Arry epics including The Parchment.
From SiT, Wasted Years and Heaven Can Wait are practically a given. Strange in a Strange Land is very likely. Before Steve's statement, I would have said they'll never play Alexander the Great, but now I'd say it's 50-50. I'd also call CSiT 50-50.
