This is one that we should be really hoping for, because it has actually never been released outside Japan. Unlike Dragon Quest IV, which just hasn't been released outside Japan in a long time. But with the Enix side in charge of Square Enix, and with Dragon Quest IV selling like it is in Japan, expect to see the money spent for localization of all three remakes.
Dragon Quest V features the ability to catch and tame monsters. Much like Torneko's quest in Dragon Quest IV spun off into its own game (and then the Mystery Dungeon series in general), this mechanic was the genesis of the Dragon Quest Monsters games.
Japan loves their Dragon Quest.
