Are there any properly-sized stadiums in San Antonio other than the Alamodome? That would probably be their only option in Austin/San Antonio, unless there's another one in SA that I don't know about, or they want to be stupid and play in Royal Memorial.
If they are only playing 25 shows in North America (with large markets likely getting at least 2 shows), they probably won't be playing San Antonio since Houston and Dallas will be higher priorities.
