There has been talk within WWE about moving the NXT television tapings to a bi-weekly style, as opposed to every four weeks.
The negative in doing something like that is that the expense for the tapings would increase, which wouldn’t be ideal considering they don’t bring in much revenue with those shows.
The positive is that the show will come off better, since in most cases the crowds for those shows are hot for the first two tapings and then die off as the rest of the tapings take place.
Additionally, this could result in TNA having more competition if and when they return to Orlando for Impact Wrestling tapings.
