Revealing too early can be more of a headache for a studio. Neil Druckmann touched on this not too long ago:
There's a reason we're still awaiting a new Naughty Dog game announcement. According to Neil Druckmann, it's to reduce pressure on teams.

“We did announce Uncharted 4 and The Last of Us Part 2 way in advance, but that actually caused a little bit of the work-life balance issues that we’ve sometimes had at the studio,” Druckmann said. “By delaying that announcement a bit, we could play with the schedule more and we’re more conscious now about how we’re approaching production. So there’s our [The Last of Us] multiplayer project and there’s another project that I will not say anything about that’s beyond that that we’re also very much excited for.”
In the PS4 gen by the end of 2016 Sony had announced almost everything they had left for the remainder of the gen, and the next 4 years worth of events consisted of showing off content they already revealed. They blew their load early and it worked to build hype, but as we can see in the above comment, revealing too early can have negative effects.
At this point in time, we're aware of roughly 15 or so SIE published titles that have either been formally announced or acknowledged by the devs. Those being:
Fairgame$
Concord
Marathon
Destiny 2 The Final Shape
Wolverine
Rise of the Ronin
DS2
Stellar Blade
Lost Soul Aside
Convallaria
Spider-Man 2
Helldivers 2
TLOU Online
London Studios live service game
KOTOR Remake
Claiming that they don't give a shit is a misinformed take. They've got a sizable chunk of announced content and based on known/speculated projects, they've likely got a couple dozen more incubating in the background for later in the gen. And as always, it's important to remember that pandemic delays have pushed things back for pretty much all studios across the industry around a year or so. If they're not ready to reveal then why add more stress to the studio just to shit out a trailer early? Let them work on the game and do a reveal when they're actually ready. That way they can spend more time working on the actual game rather than possibly wasting months polishing a vertical slice for a trailer, which is something that was a common complaint as devs prepared for E3.
