It was known for a while, specially after the trademark was found, that Dragon Quest Monsters 2 was coming. Following the success of Dragon Quest Monsters: Terry's Wonderland 3D, Square Enix revealed a Dragon Quest Monsters 2: Iru and Luca's Wonderful Mysterious Keys remake for the 3DS.
Dragon Quest Monters 2 will incorporate the content of the two versions of the game that were released on the Game Boy Color, Iru and Luca. In this Dragon Quest spin-off players can capture classic Dragon Quest monsters and pit them against foes. The game will include over 800 new monsters including super G size monsters, 4 on 4 monster battles, 8 player multiplayer, and local and worldwide communications along with StreetPass funcionality.
For now, there was no confirmation for a possible release in the west, but when considering the fact that the original games were released outside Japan, we can only hope the remake does the same.
