The Dragon Quest 25th Anniversary Famicom & Super Famicom Dragon Quest I, II, III collection (that's the title!) shows more interest in completeness than Nintendo's set, however, packing the Famicom (NES) versions of Dragon Quest I, II, and III, along with the updated Super Famicom (Super NES) versions of the Dragon Quest I & II cartridge and Dragon Quest III, in a single package. It's slated for release this September in Japan.
Technically, translations for all three games exist, since all three were released in North America on the NES. However, given that they were NES-era translations, some freshening of the text would probably be required before releasing them these days.
