ArcheAge in Japan was actually signed in 2009 (according to February 25th's press release about Simplygon), details of the company's plans for the game just recently became clear: GameOn's parent company, NeoWiz, aims to distribute and support ArcheAge using a revived social gaming platform called Pmang combined with GameOn.
It's not exactly the announcement Western ArcheAge fans want to hear most, but the news that the game will be published in Japan is definitely a step in the right direction; adding yet another country gives hope that the market will continue to expand, perhaps finally to North America and Europe. Also fanning the flames of hope is talk that NeoWiz may take the platform worldwide. We have our fingers crossed!
