A 記事 from "Dream Seed" put through Google translate discussing the striking similarities between China's Cortana and Baymax. If I find a native English 記事 instead, I'll post it.
In Japan, the film is called "Baymax" (ベイマックス). This link will 検索 "ベイマックス" on Disneystore, 表示中 all of their products. When their December release 日付 gets closer, and they create a page, I will link to that instead.
