Possible explanations
- Nintendo is publishing and they're translating it to the other 4 EFIGS languages
- Nintendo is publishing it but with the acquisition by SEGA the deal had to be reworked (which doesn't explain EO:U but Nintendo)
- Nintendo is publishing it and they're delaying it until they can do some cross-promo with SMT x FE
- Nintendo isn't publishing it anymore because they are cunts
Nintendo never announced that they'd be publishing it. We literally have no clue who's planning (or planned) to bring this one over.
