I don't expect much. Their main focus will be on TLoU2, Days Gone, Spiderman, Ghost of Tutshima, and most likely Death Stranding.
It's an impressive list and deserves attention, which I think will be Sony's focus. I think we might get a From software game from them, maybe. But most of Sony's main first party studios have either just released games lately or have their games announced.
We might see what housemarque is developeding next. Their next game won't be an arcade game and they announced they are moving away from that genre, so their next game, while I doubt will be AAA, it might be interesting.
Honestly I don't expect much in terms of announcements. Maybe they will have some surprises up their sleeves, but I honestly doubt that. Maybe a new Song Japan title might be announced
