I myself wouldn't take issue with them expanding the size of the island, along with the rest of the gaming area, including oceans, if it isn't too much of a task for them. I'd like it if they could pop in more islets, or even create an entirely separate island next to our current one. Maybe it's beyond the reach of the coders and programmers at the moment, but it wouldn't go entirely against the lore. Whatever beings could bring humans, various creatures from all across prehistory, those obelisks and artifacts together on one bubble shielded island could raise another island and bring in more prehistoric wildlife, or even creatures from the distant future and alternate timelines. We could invent new creatures and landscapes to create and fill in new roles, but also stay in touch with the lore of things and have our dinosaurs. Maybe floating islands or solid cloud-like masses in the sky could offer more in the way of vertical exploration and discovery, offering unique loot, materials and wildlife. A wild Quetzal could easily take refuge and nest on gravity defying landforms, where a daring player could soar up on their flying mounts and snatch their eggs, giving Quetzal a reason to fight if caught.
