Famitsu issue isn't out yet but here's what Japanese insiders are saying
Adol looks like a young boy, around the age of Ys I & II.
A woman who looks to be the main heroine is shown. Uses a one-handed ax. Their arms are connected by an aura-shaped string/cord.
1 versus 1 combat is a focus, with huge changes to the party member switching mechanic and weapon attributes. Personally, this seems akin to Ys VI, though isnt entirely certain yet.
Souls-like inspirations are stated, but not overt.
Kondo: I cant say which platforms that it will be on, but we wanted a wide range of users to enjoy the game, and lowering Adols age may be a part of that goal. We are working on various of platforms for its release.
Our teams Ryuji translated the following points:
Falcom wants to make older Ys titles playable on current hardware.
Mentions an emphasis on providing new gameplay, as well as new scenarios, actions, and systems.
