I won't be too surprised if the set lists stay fairly similar for a while at first. You have to remember that Mangini is new to the band, and all of the songs aren't ingrained in his head like they are for the others. That will come with time. Also remember that on both Sherinian and Rudess' first tours with the band, the set lists pretty much stayed the same the whole way through the legs (DS on the Awake tour in the fall/winter of '94, and Rudess on the M:2000 tour in the spring on '00). And the band's discography is much larger now than it was when they both joined, so there is a lot more material for Mangini to learn on the fly than there was for DS or JR.
