Elmofongo: Here's some interesting news:
bansama: Nothing interesting about it at all from the viewpoint of Japan or GOG. As you'll notice by their response*, they are very clearly stating it would only be for some regions. Japan not being one of them.
* Which is "Kitase said that Square Enix now sees the potential in territories where PC is a more popular platform." -- And this despite Japanese fans constantly trying to tell Square they want the same access to games as ROW. But like every other home-grown Japanese publisher, they ignore these requests.
It's a start, but yeah, Square having any real presence on PC is still a ways away. The only game I could see them bringing to GOG for the time being would The Last Remnant. In any case, I think Capcom and Sega are are more likely (and more interesting) targets.
