The last 1st party title teaser we had was for Wolverine. This happened in 2021.
If Sony is going to show at least one first party title presentation at today's SoP, this would be great.
On the other hand, "over 20 games for PS5 and PSVR2" sound interesting nonetheless.
Even if they'd show ten remaster/remake announcements (some of them could indeed be great though, Killzone 2/3 or Bloodborne), there still would be 10 games left.
