Far as I know, XSEED contracted the fan translator as a consultant on the project. While they're using that translation as base, they're still doing reworks on it to make sure it's as best as it can possibly be. Plus, with their PC releases, they go all out on them to make sure there's plenty of video options for newer end PCs. Plus XSEED is just a publisher, not a developer. So I guess it's understandable how long it takes, what with how little they are.
But yeah, I imagine it'd release for around $20 tops. I'd rather buy it and just play it on Steam rather than import it. Way too pricey for me right now.
