2023 will be the year of Game Pass for PC and game pass in general. The addition of Blizzard games to the service will be a game changer. The new games from Bethesda and Xbox studios will accelerate that. I always believed that the Activision Blizzard deal was more to the PC front than Xbox.
The question is how much will the service cost by the end of the year. It won't be at $10/$15 for sure. I think it will be $11.99 for the basic subscription and $17.99 for the ultimate.
