Think there will be any more dates announced?
Wouldn't surprise me.
Looking at their tour right now - there is a gap between Concord NH (Oct. 10th) and Worcester MA (Oct. 18th) - seems a bit early in the tour to take a week off.
Another gap between Milwaukee WI (Nov. 1st) and San Antonio TX (Nov. 9th), although by that point in the schedule, that could be real time off.
Next stop after that is Tuscon, AZ (Nov. 15th), so some more spots could be added there.
The gap between San Jose, CA (Nov. 20th) and Durham, NC (Nov. 27th) makes sense for the equipment to make a cross-country journey, but the only other stops after that are Orlando FL (Dec. 2nd) and Atlanta GA (Dec. 4th), so I fully expect a few more shows to be added to the Southeast portion.
All in all, there is definitely room for more shows, and I expect more to be added.
