Why have I given up hope? Well, simply because Hasbro seemed to take enough offense with some of the content from the first three Japanese G1 series (renaming the Breastforce as the PC-sounding "Chestforce", cutting out subs for dialogue talking about reincarnation, etc.). If they're so much a "family-based company" to be bothered by those little things, then what chance does Zone have without some major reworkings to its content?
What "content" does Zone have I'm speaking of? Well, the human sidekicks. Two young boys, Cain and Akira. Two effeminately-designed boys. Who are underage. And are pretty apparently homosexual. With each other.
Let that sink in for a moment.

If Hasbro/Shout! are bothered by kids watching these DVDs and being exposed to such mildly questionable concepts as the mentioning of the word "breast" and what "reincarnation" entails, I strongly doubt that apparent implications of homosexuality between two underage boys will fly well with them enough to let Zone get released without some major editing done to its content.
