I am very conflicted. Not sure if want
My guess is it'll be priced similarly to the Royal Edition upgrade for FFXV
I doubt we'll get a new world, though I could see them expanding Twilight Town. They should.
Outside of that, new cutscenes, an even more secret ending, Critical Mode, and a coliseum/battle arena will probably be what we get.
I doubt we get a colisseum. We'll likely get Super Battle Gates
