Pokémon fans have news anxiety.
I could elaborate, but instead, I will say this:
To be fair, we do know less than usual for a new generation at this point in the news cycle. By July 22 in 2013, 2016, and 2019 we knew the following for each game:
XY: the starters, the box legendaries, the release date, the region name and map, Fairy type, PSS, Pokemon-Amie, Sky Battles, Horde Battles, roller skates, rideable Skiddo, Gogoat, and Rhyhorn, the evil team, the professor, the rivals, 3 gym leaders (Viola, Grant, and Clemont) and 15 other Pokemon (Gogoat, Helioptile, Fletching, Pancham, Noivern, Vivillon, Spewpa, Skrelp, Clauncher, Talonflame, Scatterbug, Litleo, Flabebe, Honedge, Inkay, Malamar, Pangoro, Spritzee, Swirlix, and Trevenant)
SM: the starters, the box legendaries, the release date, the region name and map, the Rotom Dex, the professor, the rivals, Hyper Training, hints at Poke Ride, Zygarde's forms, and 19 other Pokemon (Komala, Rockruff, Pikipek, Yungoos, Grubbin, Drampa, Togedemaru, Vikavolt, Cutiefly, Bruxish, Charjabug, Tapu Koko, Salandit, Bewear, Mimikyu, Wimpod, Bounsweet, Comfey, and Mudsdale)
SwSh: the starters, the box legendaries, the release date, the region name and map, the burst gimmick, the Wild Area, the Y-Comm, the Rotom Bike, Corviknight Taxi, the professor (and Sonia), the Champion, one of the rivals (Hop), 3 of the gym leaders (Milo, Nessa, and Bea/Allister), and 10 other Pokemon (Corviknight, Wooloo, Gossifleur, Eldegoss, Dreadnaw, Yamper, Impidimp, Duraludon, Alcremie, and Rolycoly).
Compare that to now where we only know the starters, the legendaries, the release date, the professors, one of the rivals, the co-op and 3 other Pokemon. Hard not to feel shortchanged if you've been following news cycles for past games. The difference between what we got in past games and what we have now is stark. We know a lot less Pokemon for starters, and they'll usually have gone into detail about multiple key aspects of the game by this point when we still have questions about nearly all of them for SV (What's the region name and map? Are we getting gyms or something else? What's the burst gimmick? What are we doing for field abilities such as Surfing and Flying? Are we getting the bike or riding a Pokemon? How does the online work? Are there any other key gadgets, features, or gameplay modes we should know about?). It's definitely not just news anxiety, we know a lot less about the games and we have many more unanswered questions at this point than we did for past games. I'd say concerns about the lack of news are justified at this point.
