The old TRL studio was about one story up in the first version of the series, and McCarthy did not indicate whether the new studio would be a revamped studio in the old location or perhaps somewhere else in the Viacom building.
McCarthy did note the show will hopefully utilize the pedestrian plaza in Times Square for concerts and events in addition to the alleyway near the Viacom building, though, so maybe the location is getting a bit of a mix-up.
Like its predecessor, the show is scheduled to run for an hour, although McCarthy teased that duration could stretch to an additional hour or two as they play with the format.
