No Dragon Quest news came out of E3 from either Square Enix or Nintendo. Underscored by the poor sales of Dragon Quest X on the Wii U, Dragon Quest has officially been abandoned again in North America. Square Enix simply cannot get their act together and made a horrible decision in making Dragon Quest X an online-only, subscription based game.
Dragon Quest was dead in North America from 1992-1999. Looks like we are entering the second "dark age" for the game series which is arguably the best selling series of all time in Japan.
