What else do you want?

Are you even going to have the time and money to play all these games?
This drama about a "showcase" is becoming a joke, Sony has been getting away from that kind of marketing for years, they want to have a continous flow of announcements and not have their development teams being forced to announce stuff early just to meet the date of a specific event. They'll announce their next round of first party projects when they're ready and not necessarily in a single huge show. Indeed Death Stranding 2 could be announced at TGA.
