If any of the other Japanese TF series are an indication of the quality of this series, I probably won't miss much if this series is never released in other regions. In my opinion, the Animeformers series are garbage. But, since other people seem to want them released here, I won't argue against it.
Takara is/was(their Prime toys are awful, stickers are so 1984 and not in a good way) a good toymaker, but man do they blow at making good Transformers cartoons. In my opinion, G1, Beast Wars(the Takara version is nauseating
), Beast Machines, Animated, and Prime are infinitely better than the Transformers anime series.
