That is what I'm talking about. I dont forsee the game playing drastically different now that we know about jobs and having more party members
Fighting battles 1 vs everyone, versus playing battle with a party of 4 vs everyone will definitely change the feel of the battles a bit I think, if the new demo features gameplay with a full party.
Clearly if you want gameplay in realtime like Ys or Tales or something, that isn't this, and this will never be that... so I guess it just depends on what you're expecting to change.
Edit: I guess upon reading the thread a bit closer, it'll just be the first chapter of the characters, so it seems doubtful you'll have full party combat, so you're most likely right, this won't be too much different from the prior demo's combat I think.
