Since the localization's announcement, it was questioned if YW3 will be 2-3 versions like Japan, or a single version.
These tweets confirm that it's a single version based on the third version with more enhancements and that every Yo-kai can be obtainable in it.
That's actually pretty cool, and feels like a nice set-up for the franchise's future of only doing one game (Yo-kai Watch 4 will only have a single version).
Kind of feels like we're getting a definitive version. At least Europeans and Australians will be getting it tomorrow. Us stupid Americans have to wait until February.
