>And don't give me >b-but B2W2, because they substantially deviated from the plot
USUM will deviate from the plot as well, about as much as Emerald or Platinum, but okay, I'll give you this one because it ain't an actual sequel.
>and hugely increased the regional dex (by 145),
USUM has been confirmed to at least have 400 "new" mons, whatever that means. That's at least 100 more, thus being an even bigger dex than XY.
>added an extra 1/3 to the region
There's huge clouds on the map hinting towards it, besides new areas having been shown in the trailers. Might not get any new towns, but we're sure as hell getting a bunch of new areas.
>and had multiple post-game activities.
Photo booth (with props and stuff that have to be unlocked, some of which probably post-game) and mantine surf, are both confirmed right now. We don't know how much depth they offer but they are probably optional, meaning "extra content", even though not necessarily post-game.
There's probably more stuff to come, we're still a full month away. Besides, do you really expect them to blow their entire load this soon?
