Last week's issue of Famitsu hid more in its Japanese text than just the June 23rd release date for The Legend of Zelda: Phantom Hourglass. Zelda Universe's novice translation of the scanned pages indicates that the title might support online voice chat. Though this feature doesn't seem useful beyond setting up matches and trash-talking with your friends, it's a nice addition to the meager multiplayer mode.
With upcoming games like Pokemon Diamond/Pearl and Panel de Pon also planning to use the Nintendo DS' VoIP capabilities, purchasing the uncomfortable-looking, official headset is beginning to make a lot more sense to us. Of all the titles we expected to eventually include voice communication, Phantom Hourglass was definitely not one of them.
Update: Having a bit more experience with the Japanese language, The Hylia translated the Famitsu scans in an effort to confirm this news. Much to our dismay, The Hylia found that there is no voice chat support planned for The Legend of Zelda: Phantom Hourglass.
