We don’t know if these new registered trademarks are related to EchoChrome, but it’s a fair guess:
echoBLACK, echoSEPIA, echoWHITE
There’s also two new ones:
Dark Mist, Treasures of El Dorado
No idea what Dark Mist is, but Treasures of El Dorado is probably the Japanese name for Uncharted. More as we get it.
