That's not quite the same though. There's no expectation of DLC there, from either fans or SE themselves. Any new content for FF7R should be in FF7R part 2 rather than in DLC/a re-release of the existing game.
I think an ultimate edition or some such is pretty much guaranteed when all of the FF7R parts are finished though.
XV is a unique stain in the franchise though. Everything else around it has released in a complete state even if I haven't loved the games themselves. I think they'll more likely go the route of sequels/part 2s in future if they want to monopolize off a single entry.
