SquarePenix: I'm actually working on writing an article regarding digital distribution and the JRPG. Another significant issue comes about with parity in the gaming industry. With increased game development cost and there no longer being a "lead" platform, JRPGs are difficult. No longer can a publisher or developer push them out for the PS2 and know that the majority of their owners are going to have that console. Your audience is splintered and development cost is increased if you have to publish on multiple platforms.
Wizardry's a unique bird, too, because of the lack of localization assets. If you were to compare, say, Wizardry to, Legend of Heroes: Trails in the Sky, you're likely looking at a difference of thousands of man hours. Translation is difficult, voice acting is expensive, and localization is important now, too. We don't accept spoony bards or Chaos Wars anymore - not unless the joke is on purpose.
Digital distribution is a good step, but I don't think the current RPG market supports it, at least not for consoles, and few JRPGs are developed for PCs. Question there, does XSEED localize Falcom's stuff for PC and put it on Steam? I'd find that very interesting.
