The revealed sword is certainly a unique take on the classic Power Sword from the original series. Hopefully this means the other weapons will be revealed as New York Comic Con gets closer.
The Power Rangers film is currently being produced by Haim Saban, Brian Cassentini (of Saban Brands), and Allison Shearmur (Cinderella), with a script written by X-Men: First Class and Thor writers Ashley Miller and Zack Stentz. The film is being directed by Dean Israelite.
The film hits theaters March 27th, 2017.
