^ They could always adapt Goseiger for the 19th season of Power Rangers, leaving the Kaizoku season for the Anniversary season of Power Rangers.
Which is how things are shaping up right now.
Power Ranger Samurai 1-20
If successful in the spring 20 more episodes will be ordered
2012-Goseiger adaption hopefully will follow the same pattern
Fall 2013- 20th anniversary.
I just having a feeling Bandai of America will screw up the toy line since the Samurai line looks atrocious.
