Update (2016-04-23): Nintendo Everything has recorded footage of Nintendo showing off the latest Tokyo Mirage Sessions #FE footage for Twitch, added to the bottom of this post.
As announced previously, Tokyo Mirage Sessions #FE is currently playable at PAX East 2016 in Boston, at Nintendo’s booth, and GameXplain have released over 20 minutes of off-screen, English gameplay footage from the playable demo.
20 Minutes Off-screen Gameplay
No audio for the game could be heard from the showfloor, so GameXplain added their own audio which is not from the game itself.
Tokyo Mirage Sessions #FE (previously known as Shin Megami Tensei X Fire Emblem) was released on December 26, 2015 in Japan for the Wii U. It will release in North America and Europe on June 24, 2016.
