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