The planĀ is for WWE to use footage from NXT Takeover: London, the three matches that were taped at the show, and some recap shows to fill three episodes of NXT TV until the company holds their next TV taping at Full Sail University on January 7th. WWE would then tape three more shows on January 22nd at the CFE Arena in Orlando (University of Central Florida Gym) and three more episodes on January 27th.
This would leave them with enough content to air on the WWE Network until mid-March. The NXT Takeover: Dallas card is expected to be revealed by the January 27th TV taping.
The reason for WWE taping so far in advance is because the NXT crew will be outside of Florida doing more touring in February and March.
