This is hopium powered speculation but hear me out. The leaks suggested that GF were at the very least considering a gen 1-4 MMO. Now, what if that will be their way of doing remakes going forward? They could follow with a US based MMO in gen 11 (Expanded Unova, Orre, Alola, maybe something new) and a Europe MMO for gen 12 with Kalos, Galar and Paldea.
Here's hoping that the world doesn't end by then.
