Whoa. Okay, then it must get released in NA, right?
Disaster: Day of Crisis, Tingle's Rosey Ruppeeland, & that Fatal Frame 2 Wii remake say "hi". Even if it does come out in NA, it'll flop just like all the other DQ games have. I wouldn't be surprised if they got outsold by the Danganronpa games on the Vita.
Dragon Quest IX was a success with help from Nintendo, same for other niche Japanese games like Monster Hunter, Bravely Default and Fire Emblem, so long as they don't push them out the door with little to no fanfare 7 & 8 could do great in the west.
I won't believe it till I see it but this would make sense, Horii has been talking about how he wants to reinvigorate the brand in the west starting with Dragon Quest Heroes, and Square Enix did recently send a cease and desist to the fan translation...
