Seems like it will, ms was just trying to figure out how to monetize the addition as much as possible.
My guess:
Xbox Game Pass Core (Xbox Consoles) - $9.99/month. - stays the same
No newer games like now. Adds some older cod titles.
Xbox Game Pass (Xbox Consoles) - $10.99/month. - goes up to $12.99
Includes all new games including activision
Xbox Game Pass PC (PC Platforms) - $9.99/month. - goes up to $11.99
Includes all new games including activision
Xbox Game Pass Ultimate (Xbox Consoles and PC Platforms) - $16.99/month.
Includes all new games, including activision
Price stays the same now, goes up a few months later, quietly.
