Before San Diego Comic Con 2014, Kyoryu Sentai Zyuranger was only known in hushed tones in America. It was, like most Super Sentai, available via fansubs, but never had a legitimate release in America, thanks to Saban using its footage for Mighty Morphin’ Power Rangers.
Before San Diego Comic Con 2014, Superdimensional Fortress Macross was only known in hushed tones in America. It was, like most of the shows that formed Robotech, only available in rare releases in this form.
Both are coming to DVD.
It’s not a definite sign that we’ll see more, both releases are of the most iconic in the franchise, not more recent series that just have never seen the light of day in America in any fashion. 2012’s Tokumei Sentai Go-Busters and 2008’s Macross Frontier could be introduced down the line, but releasing these is a start.
