The first link is to a blog post that I stumbled upon; it leads to the article in the second link. It’s mainly about a new system called ADAMS, for creating "adaptive music" in games. Basically, this system would change the character of the music based on what’s going on in the game; I didn’t read into much detail, but it sounds pretty excellent.
What’s most interesting, though, is the tantalizing bit where the article refers to an "unannounced game" that Tsuchiya Akira is working on, expected to be released next Spring. Tsuchiya’s demonstration images in his presentation used Ar tonelico 2 art, and the series is overdue for another entry, considering that three Atelier games (Mana-Khemia 2, Atelier Rorona, and Atelier Annie) have come out since At2. And what better game to use an advanced music system in than the intensely music-focused Ar tonelico?
This is pretty exciting; if the game is due in Spring, we should hear an announcement very soon!
I am pretty confident that Ar tonelico 3 will be a PS3 game. GUST finally committed to the platform with Atelier Rorona. I see that game as a way for them to build up their codebase and development chops on PS3, so that they’ll have some experience before tackling the next Ar tonelico, which needs to live up to its legacy as GUST’s new (relatively) hit series. GUST relies heavily on shared engine code between their games; moving to a whole new platform is a huge deal for them, and I doubt they’re going to look back to PS2 or switch platforms now that they’ve started their PS3 journey. (That doesn’t rule out hiring other development teams to make side-games on other platforms, like the Atelier titles on DS, but they wouldn’t do that for a flagship title.)
As for the music system being used in the game, the article says that Tsuchiya and GUST have spent 10 months working with a beta version of ADAMS, in an unannounced title, and that this title will be the first product to use the system. So there doesn’t seem to be much doubt that the next GUST game will have the ADAMS system in it. Also, the article is pretty specific in saying that this unreleased title will be announced within this year, and released next Spring.
As for a fan translation, if NISA doesn’t take it on for some reason, it would likely have to be a text script to read along with (like the Xenosaga Madness Project or Kayama’s Sakura Taisen scripts) rather than a patch. I don’t think that PS3 hacking has gotten to the level of patching games yet, has it?
