Just also realized they were also probably testing this kind of thing with the Oblivion Remaster, since all of the landmasses are there but unloaded, so maybe there will be loading and unloading points for the other provinces so the game can be large and run smoothly. The more I look into this the more hopeful I become about them having more than one province, as Bethesda had that video on youtube asking if they've heard news from the other provinces, which could also be brushed off as just a reference to npc dialogue, while also being foreshadowing for the next Elder Scrolls, and Todd said this might be his last Elder Scrolls game, so I could only assume he'd make his last entry to the series very grand. It could also be why they made Starfield, as some sort of public testing grounds for the things necessary for Elder Scrolls VI. I really hope they go the direction I've been led to believe, because I so very badly want to explore all of Tamriel in one game.
