According to the Megadeth forums last nights set in Boise was the same as this show. So i'm guessing that this will more than likely be the set for the whole RIP 20th anniversary tour. The review also said that Testament is just doing The Legacy and nothing else.
They also said this was the Exodus set:
The Last Act Of Defiance
A Lesson In Violence
And Then There Were None
There, everyone should be happy we know all the sets now
