As of right now I believe we have:
The Woodlands
Round Rock
Claudia Taylor Johnson
Hebron
Pearland
I think CTJ is going to be every other year now along with the Woodlands and Round Rock, and Hebron has confirmed internally for a while that they will be back in 2023. Pearland has confirmed a trip, and I think there are a few other bands that are rumored, some of whom would be first-timers.
