I think it's super unlikely, almost imposible, to see there the next Sucker Punch game.
Ghost of Tsushima Director's Cut / PS5 patch / Ikki Island DLC were released less than 2 years ago, and a few months before they released GoT Legends.
Nowadays Sony prefers to announce and show their games when they are pretty close to their release and I think won't be the case if they only have been working on it during 2 or 3 years.
I think it's way more likely to see its PC port instead.
It also had REVII reveal, an Horizon gameplay demo (not the first one), PSVR stuff and TLG final release date.
