Don's solo set lists tend to be the most interesting and adventurous out of the Eagles. There's a chance that they'll perform No Thank You but Don likes to be faithful to the album version. I expect Vince's Heartache Tonight will be closer to the original than Glenn's HOTE Tour version.
I saw an Eagles tribute set list that opened with Hole In the World and Heartache Tonight, obviously referring to Glenn's absence. I'm expecting a procession of hits but Don does pay attention to the lyrical content of songs so tracks specifically about loss, closure, rebirth etc. may sneak into the set list.
