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