Please. This was the big comeback showcase, meant to kickstart the next stage of PlayStation. The fact they had nothing to show from first party 2024 releases speaks volumes.
Comeback ? A comeback from what ? Winning ? Because in the competitive landscape of gaming, that's what they've been doing with PS5?
The problem, it seems to me, are your expectations. I'm not saying this to be combative, just to stress that you seem to be placing way too much emphasis on this singular showcase, when its just the start of the season.
Look at how the content was selected; it was a mixture of short term stuff (FF XVI, Street Fighter), far-off announcement reveals (Marathon, Metal Gear). Some AAA stuff from EA and Ubi, some indies, etc. etc. The commonality was that it had to be flashy and "cool looking", for want of a better description it took a "shock and awe" approach. Which was why there was so many cinematics and so little gameplay.
Its weird, do you expect Sony to show big titles/franchises that have been previously revealed at every showcase? Because that's absolutely not been their MO for a long time now. They reveal, skip a few opportunities, then spotlight again closer to release. The absence of Rise of the Ronin, or Death Stranding 2, or Silent Hill doesn't mean they've been cancelled or delayed.
