Gokaiger won't be adapted. The claim was it is too hardcore for kids
You may be wondering why Power Rangers Megaforce used Goseiger rather than Gokaiger, which was an ideal season based on the successful execution of the anniversary concepts. I wasnít able to get a solid answer for this question. They believed that Gokaigerís pirate theme was more focused for boys (rather than boys and girls) and the concepts of stealing and plundering were too hardcore for a young audience.
Well this sucks for people that wanted this season adapted
