Shout! Factory sets a release date for, the first volume of Next Mutation for September 4th, 2012. It is not know at this time if the episodes will be uncut/unedited. However given how much love and care Shout puts into their releases, I am willing to bet they will do everything within their power to make sure they are.
Update: Straight from Brian Ward of Shout! Factory’s Twitter Account: My Question: Will the episodes be uncut/unedited unlike the UK release by Jetix?
Brian’s Answer: Was never under the impression that what I had WASN’T complete.
