Here's my Hope and Cope
- Majority of the presents will be dedicated to Mobile Game info. Besides the various Gachas I don't keep up with, Pokemon Go is wrapping up its current Season with Go Tour Sinnoh and Origin Palkia/Dialga. This seems like the kind of time that game will drop its next Month/Season Roadmap with stuff they can't quite find a big in-person event for but will generate hype, such as Remaining Meta Megas (Lucario, Heracross, the Mewtwos, etc). They already confirmed other subjects of speculation aren't in the cards atm like Arceus or Manaphy, and I feel like hard confirming that would only occur if they wanted people to speculate on "well then what CAN it be?!"
- Some TCG news since they have the Kitakami themed stuff coming, probably tease at something for ID related mons and keep that merch machine going.
- SV announces some upcoming Raid event for another transfer-only set of Mons. Stuff I speculate on includes Calyrex (to go with the Horses being in the DLC), Zacian/Zamazenta for Eternatus later, or Keldeo for a "training" event and because it's the only "regular" mon with a connection to Paradox Legends still missing (Ho-oh is in for the Beasts and the regular Swords are all from Snacksworth). Or maybe it's just a Sinnoh spray because of the Sinnoh Tour stuff since people will have caught a bunch of Legendaries in connection to it and need an in-game encounter to allow their transfer.
- A tease of some game for the Holiday Season that, mainline or not, is intended to be significant enough in scale to be their focal point there. People are going to be antsy about straight Unova remakes after BDSP, but I also have my doubts they do something like that since most of the Unova Legendaries are available in SV after the DLC. If I were to bet, I'd expect either a Legends Game again or something like Home-Compatible Ports of older games to futureproof against Bank's eventual closure.
-- My doubt against something like Black Shadow and White Lightning or something is that the Unova games were the first ones to have direct sequels in mainline, and compared to something like the Orre games, B2W2 explicitly follow up on events and threads from BW, such that from a branding stand point one game is incomplete without the other, compared to how Emerald or Platinum content was stuff they could roll into dual remakes (didn't but had the ability to).
-- A lot of people speculate on a Legends Unova game because of the Unova focus in the Indigo Disk, but I'm iffier there. The only Gen I can think of that heavily referenced the Remake-Region in its corresponding main entry is Sinnoh having things like Jasmine's Cameo or the mention of the Rage Candy Bar being out of stock in Veilstone. RS barely bring up Kanto and even Colosseum was mostly for the Johto Mons that were missing, Kalos was more a Kanto fest because of the Anniversary, and Galar I can't think of many Regional references in general outside Meta things like the Gigantamax focus on Kanto mons. Additionally, Legends Arceus focused on Sinnoh which happened to include the missing Mythicals from SwSh's roster even with transfers, so I'm willing to speculate this hypothetical game would do similarly.
-- With the above stupidity on my pattern recognition, I'm led to expect a Legends Kalos game, as people speculated on heavily with the Iberian Peninsula basis for Paldea, the explicit absence of the Kalos Legendary trio, extremely underexplored lore for the region, and 10+ year gap with XY's original release in such a release season (Legends Arceus being 14 years after Platinum given how many elements it draws from like Giratina's post-game conflict and the Origin Forms given to Palkia/Dialga).
I doubt any Gen 10 news until Nintendo confirms whatever and whenever they're doing for new hardware, as two Generations is the most any Console has received, even on something as big as the DS. Maybe we get a sneak peek Pokemon ala Meltan or Bonsly, but nothing like a region tease for a while
