Internet sleuth superannuation reports that Namco has filed a new trademark for a game called God Eater. That's about it, really. The trademark page does refer to it as a game "that may be accessed network-wide by network users via mobile phones and computers," meaning it might be a downloadable title. We are decidedly not experts of trademark language though, so it's anyone's guess.
We may not know what the game is about yet, but we know one thing: Writing the theme song should be a snap.
