I'd like to believe that having it added back as DLC is a realistic possibility (hell, I'd take it as paid DLC), but I can't imagine it actually happening. It'd require quite a bit of additional localization, not just text but lots of extra voice work as well. But at the very least, I think people should still speak up and make their perspectives known, and hopefully Nintendo may see that and maybe things will be different with the next Fire Emblem. But it's a decision that's disappointing a lot of people, and I think that should definitely be voiced—but preferably in a positive manner. Fates is still a fantastic game, after all, and I think people should definitely pick it up and support it, even though we'll unfortunately be missing out on content outside of Japan.
