Prospects for Future Studies of the XYZ: BESIII, GlueX, Panda

The unexpected XYZ states of charmonium are still yet to be fully explained. Further progress will require additional experimental input. This talk will review the prospects for future studies of the XYZ states at BESIII (in Beijing, China), GlueX (in Newport News, USA), and Panda (in Darmstadt, Germany).
