No official announcement has been made, but AQ Interactive wouldn’t trademark Away: Shuffle Dungeon in North America unless they had a plan for it. Would they do this just to tease us? I think not. Since Mistwalker and Artoon’s DS game isn’t even out in Japan yet I wouldn’t expect an announcement to come soon. However, this is a first indication that someone (XSeed?), somewhere might be working on localizing Away: Shuffle Dungeon.
Interesting note related to AQ Interactive and trademarks they also registered Cry On ~ Another Yesterday ~. Cry On is Mistwalker’s third Xbox 360 game and I wasn’t aware it had any subtitle.
