Tabata says holding down the Defend command will result in auto-dodging.
Random shiz I noticed: Tabata mentioned the "Iya... 15-banme da yo" trailer was still basically running on a bespoke FFXV engine called "Ebony," which was the first I'd ever heard of it.
They're now transitioning to Luminous, and this demo is somewhere in between.
Gladiolus is "Gladio" on the Japanese UI. Maybe the names as we'll see them in the game (Noct, Gladio, Prompto, Ignis, Cor) won't be as silly as they always seemed.
Team-up attacks are spontaneous and proximity-based.
Edit: Tabata also estimated the current build is 70-80% as pretty as the final will be.
And I'm forgetting plenty of shit Tabata said.
