Any clues as to how the whole summoning thing will work? I always liked the Evokers, even though cards seemed more fitting.

We'll be going with the tarot cards. The Evokers were used because they tied into Persona 3's themes on the fear of death and the like, while tarot cards have really been the default thing for the franchise as a whole, although Persona 1 and 2 didn't really need any form of focus to summon their Personae.

Tarot cards are also an easier identifier.
