WWE announced today that "NXT" will launch February 23 on Syfy, replacing the ECW TV show in the same Tuesday night timeslot.
As a result, there are only two remaining episodes of ECW TV on Tuesday, February 9 and 16.
WWE's website has a look at the new "NXT" logo and the promo video that aired on Superstars last night promising a "groundbreaking, original show."
