As announced a few days ago, Sony is working on Dual Hearts, a new PS2 action RPG. After meeting with Baku, a magical animal from the World of Dreams, the game's main character, a treasure hunter, will travel to Sonno Island in order to gather the Keys to the shrine of Dreams. He will have to travel through other people's dreams. Dual Hearts is still scheduled for February and you can take a look at the first piece of artwork, and one screen shot:
