Dragon Quest VIII on Nintendo 3DS will have a new dungeon with a new boss named Jahagaros, according to the latest issue of Jump. (Thanks, @kazu4281)
Jump also say they will reveal a big title in next week’s issue, and judging by the wording this is a Dragon Quest-related announcement.
What will the new game be? Your guess is as good as ours, but keep in mind that Square Enix are working on a new Dragon Quest Monsters game.
Food for thought:
The wording in Jump states that the reveal will make readers go “Nuwaaaa!” That’s a reference to Dragon Quest V.
