Several posts on Rangerboard: (Post 1 & Post 2) and RangerCrew: (Post 1 ) have stated that Power Rangers Super Samurai, the second half of the 18th Season of Power Rangers is slated to return to Nickelodeon on February 18th at 12n/11c on Nickelodeon!
It appears that Michael Madnick who is the Director of Creative Services at Saban Brands stated the series is going to premiere on that date.
Apparently, Madnick posted the reveal on Paul Schrier’s (Bulk) Facebook wall but then later removed it.

Of course this is not 100% confirmed and is a rumor at this time, but given that he is a person working for Saban Brands it’s most likely it is correct.
