Why would they care if someone else kepts getting what they were getting when they can now get more and own the product.Sony no longer has to pay for whatever deal to get their 30% of sales. M$ essentailly paid 7.75b to keep Sony from paying for the exclusive deal, and still get 30% of whats sold on their platform.
If Indiana Jones didn't go to PlayStation then what Sony gets 0, instead Sony gets what they get and MS gets more than they would have gotten plus they own them.
