Sims 4 Island Paradise: Expansion or Game Pack?

I don’t think they would make an EP out of an island theme this time around, the only way I can see an island themed EP being made is if the island isn’t a vacation world, but a normal one, similar in style to City Living, an EP about a new world and the experience surrounding the new world.

But honestly I think the island theme would be made into a vacation like game pack, probably won’t have most aspects IP had, but still a unique take on the island setting and experience.
