The baffling thing, at least for me, is that this series is perfect for a port or remake or something substantial using the older games. I remember there was a mini-flareup when Square Enix accidentally mixed screenshots from SD3 with the initial announcement of Heroes of Mana.
Or hell, just have them put up a translated version of SD3 on PSN or something. I'm sure they have some abandoned localization attempt sitting in a cardboard box somewhere, and hell, it worked well enough for Squaresoft with FFV.
