WWE returns to Mexico for their house show tour next month, and it's expected they will announce TV tapings in Mexico City for October.
The tapings would happen at Palacio de Los Deportes, and both Raw and Smackdown would be taped in advance over a weekend.

Surprised that they've never done any TV tapings there, arena holds 18K for football, so they'll prob be set up for 14k and should have no problem selling out. Be interesting to see how the crowd comes across on TV.
