At this time, WWE is planning to bring NXT to US TV in the fall. The idea is to use the show as a transitional product; similar to how the ECW on SyFy show was used in the end (introducing new talent to TV before they moved onto RAW or SmackDown).
The other reason that they are looking to get the show on TV is that a one-hour WWE show could make the company up to $100,000 a week in TV rights fees.
