Namco Bandai filed yesterday for the registration of the trademark “Lost Swords“.
You can see the result of a trademark search below. We still don’t know what the trademark is about, but considering the theme, we can try a few guesses. It could definitely the subtitle for a new Soul Calibur game or it could could also be the new Ace Combat project recently teased by Team Aces.
Of course it could be something else entirely, but those are the two most fitting options that came to mind. Other than that, your guess is as good as mine.
