we'll probably get the new Dokite package art, and at least the art book interview too
anything beyond that is a mystery but to me it's already like super ideal, i can't imagine what else they could do to sweeten the deal

thinking about all the dumb bullshit in Final Fantasy XV that you straight up cannot access anymore
the Assassin's Creed tie-in festival DLC, for example, which had crossover content with the previous Choco-Mog festival which was a limited time event that ran only twice
the PC port removing the ability for Noctis to have the appearance of your Comrades character, and maybe even the little sidequest you can have with them late in the main game (?) after they cancelled online support
the limited time event Assassin's Creed festival even had a bit of minor story content, it sorta had an extra bit to an extremely minor villain
