I wonder if the reason Europe gets the game slightly later is because of logistics in producing Amiibo, i mean sure the game hasn't actually mention compatibility with Amiibo yet, but they could be trying to maximize Christmas shoppers. it already happened with Kirby since the Japanese version of Planet Robobot has a full english script inside. at least it's less about competing with Fire Emblem and more like that they need time to produce Amiibo.
Alternately it has something to do with Dragon Quest VIII in America which was rumored to be around Autumn/Winter due to leaks. America just had Style Savvy 3 confirmed which means that Summer's release is probably Rhythm Heaven Megamix and the game codenamed "Torte City" is aiming for Autumn; it's likely Yokai Watch 2...
...Since they already localized Fuyunyan as Hovernyan, USApyon as Usapyon and Robonyan Model F as Robonyan F-Type because they used dual-languages (Katakana Japanese, and Localized English*) for their names in the Final Fantasy XIV crossover trailer where some of the Yokai appear as pets/companions.
* Names that were already changed retained the English names: so Fubuki-hime/Blizzaria, Kyuubi/Kyubi, Orochi/Venoct and Bushinyan/Shogunyan. they're probably going to replace the Taiko no Tatsujin Yokai in the english version of Yo-kai Watch 2 and replace them with the 2 Final Fantasy Jinbyan variants. they also would have to air more anime in Fall/Autumn as well as maintain Wibble Wobble. (a Phone game, but currently is capped due to not revealing Japan-only Yokai) Yokai Watch has been alive since 2013~ and only just got to the west since 2015/2016...surprised they're showing it much more love than Inazuma Eleven though.
In the past, they already tried to avoid competition, Nintendo handled western Localisations of Dragon Quest Monsters: Joker 2, but moved the game to avoid competing with Pokemon BW and moved Inazuma Eleven in the Summer so Disney could show the Anime for 2 weeks.
