I think in terms of live service titles, I don't really see anything outside of Helldivers 2 (probably close to release) and Factions being shown (end 2023/ early 2024).
I imagine Firewalk's game and Twisted Metal are further off, or at least their announcements will be made closer to their respective releases (which admittedly could be soon).
In fact, I think all their live service titles will be announced with a quick release turnover. Factions is the only exception because we already know it exists and I think marketing could still emphasis the narrative element of it.
Of course, the more the merrier at the show
