Those familiar with Monolith Soft's Xenosaga series may not know its subtitles by heart. You see, the series was spread across three episodes (despite the creators wanting to go well beyond that). You have Der Wille zur Macht, Jenseits von Gut und Bose, and finally, there's Also Sprach Zarathustra.
Why is this last point the most important? Well, it appears Bandai Namco has trademarked Also Sprach Zarathustra in the United States. For a sequence of games that have lied in dormancy for over a decade (Xenosaga Episode III was released in 2006), you wouldn't necessarily do that unless you had plans to do something with it.
This makes a strong case that Bandai Namco at the very least is contemplating remastering the trilogy, and after the huge swell of excitement surrounding .hack//G.U. Last Recode, they may very likely follow through with that plan. Let the speculation begin!
Thanks Gematsu for the heads-up.
