I'm okay with being wrong on COD exclusivity and such, along with Diablo, Overwatch etc, but upon a further reading of that statement... it literally can still apply to Warzone and mean games people can already play on Playstation.
All that's really being committed to is games continuing to be available on Playstation, which can mean you'll always be able to purchase, download and play the existing titles, along with Warzone.
Of course COD will never be exclusively available on Xbox, Warzone and existing COD games will still be on Playstation.
Even the beyond agreement and future remarks are clever, and don't ever commit to newer call of duty releases. They could have very easily said "All future Call of Duty games will continue to release on Playstation. None of the future titles in the COD franchise will skip Playstation."
And when they end by saying Sony fans can continue to enjoy the games they love. That again can mean ones they already possess. No commitment to newer titles past the agreement. And the CNBC interview I saw only convinced me further.
The minecraft example he brought up is common sense. Who wouldn't bring up minecraft when trying to get approval for this deal? More platforms is literally covered by game pass minus Playstation. Game Pass automatically spreads a game across more platforms than PC, Xbox and Playstation. Man even said "HOPE" when referring to support for other platforms.
Translation: Microsoft is setting the PR stage, and fully intends to take full advantage and make games exclusive if the acquisition clears. This was just them presenting their arguments.
