I think it is about a robot army,which would explain the robot in Zane's eyes on the poster "we will be back."If 당신 want to see a 미리 보기 just go on 유튜브 and type in 닌자고 2014.
In 2014 (which it is), The Ninjas will go against stronger enemies than ever before..........NINDROIDS! Also, Zane might turn evil in mid-season 4. I even saw a picture of damaged zane and if 당신 look closely at his right eye 당신 will notice a nindroid face.
