Well... for starters sony is the new kid in town here and will compete in the biggest jungle of them all for multiplayer: PC. On PC out of nowhere 3 guys can release a game like battlebit and steal your thunder.
And several of those games you mention have robust single player content so they can use different monetization methods. It all depends on what Sony idea of Gaas is. If it's a single player experience with multiplayer elements added on top like Forza, MK8 MK11, GT7 Smash... they can sell it for a price.
But if it's a purely multiplayer experience that lives or dies by having an active playerbase... good luck asking for full price and high end specs.
Bungie is the new kid in town? As I remember Destiny broke the record of best selling new IP in gaming history and redefined MP and GaaS in console.
And Arrowhead? I thought they made several successful and highly reviewed multiplayer games before.
Same goes with Haven, with many people who worked in games like the highly successful Assasin's Creed, Watchdogs or Rainbow Six Siege, or most people in Firewalk or Deviation who worked in many top MP games like Destiny, Halo, CoD, Apex Legends and many other top shooters.
Gran Turismo and MLB are new kids in the block too? Do you think they don't have robust single player? They are Sony GaaS.
And btw, do you know that Sony already had very successful and profitable GaaS games like PS Home and Little Big Planet before?
It is surprise but ND didn't release a single new game for the new generation and we are 3 years in the generation.
They are really letting down this gen while the previous ones they were very efficient.
They released TLOU2 three years ago, months before the generation started. Back then they had a single big team and nowadays you need way more than 3 years to release a new big ass AAA game.
Since then they released the TLOUP1 remake and Uncharted Legacy of Thieves Collection on PS5 and PC.
Plus they are working on TLOU Online which is their biggest game ever in addition to more games, being at least one of them single player only.
Every generation AAA games require more work to be made because they are bigger and more detailed. So every new generation they need more workers and more time to be develope a AAA game. Not only at ND, but in every single AAA studio.
