I very much hope we get a new environment should Scarlet & Violet receive DLC, but I can't for the life of me figure out what that could be.
I would love for us to return to Kalos, even if it's just the southern portion, but that's highly unlikely. lol In terms of real-world perspective, the only areas I could see being represented as DLC are the Balearic Islands and Northern Morocco. I'd love to see the latter, especially with connections to Alfornada.
The Balearic Islands are there, but only Ibiza and Formentera. Still missing are Mallorca and Menorca. I mentioned it before, but there are some other outlying islands under the possession of either Spain or Portugal that could be used. In addition to the remaining Balearic Islands, there are:
Canary Islands
Madeira
The Azores
And if we include Cape Verde, which is its own country, it would comprise the entirety of Macaronesia.
I think we will go even deeper into Area Zero specifically the crystal cavern section. It’s extremely empty aside from the building with the time machine and crystals and it feels like there is definitely some huge secret still hiding in the area which is probably the third legendary. The huge crystal sections that are basically individual cliffs are wider that you’d expect them to be and big enough to secretly have a cave or cavern inside where hidden Pokémon are living and possibly where the Paradox Pokémon come from as we know that the time machine created portals when it was still running and that where the Paradox forms emerged. It was never stated that the portal was in the same room as the machine and it could have easily created a time rift outside the lab.
It's probably just a visual glitch, but sometimes, Pokémon spawn inside of those crystals and you can't reach them (and neither can they reach you).
You sure love the word "heck". Anyway, I suspect the new DLC areas won't be Kalos specifically but an expansion of the Sinjoh concept. Kalos with Gen 9 graphics would brick the cartridge, I don't see them putting two whole regions in the same game.
People keep talking about Southern France, but
Andorra lies between them. If there's going to be a connector between the two regions, like with the Sinjoh Ruins lying between Kanto and Johto, it would definitely be Andorra. It would fit with the very high elevation of the location (as Andorra is located in the Pyrenees), and owing to it being mostly urbanized, you can definitely put a town there based on Andorra la Vella, Andorra's capital and its largest city.
