I'm not sure if anyone saw this, but another trailer hit yesterday. It's the Japanese trailer this time with mostly stuff we already know, but with a new addition: https://m.youtube.com/watch?feature=youtu.be&v=8oO_P4GX_RA
Yes you just saw a glimpse of Nariya Oak! He's confirmed to be Professor Oak's cousin who's studying the Alola region and the Alola forms of Pokemon!
