I get the feeling the announces are going to be like this. The rumors for “Brave” all point to characters from Square Enix RPG’s Erdrick (Dragon Quest), ? (Bravely Default), Chrono (Chrono Trigger). If Persona doesn’t come to switch then I’m guessing its supposed to represent Shin Megami Tensei.
Why this week? I would guess just after that Persona 5 stuff because whatever they announce will be relevant to Joker in Smash.
We did get that datamine that pretty much confirmed the Persona 5 R character is probably an alt.
