This is what I've been saying since the activision deal, just because they made public statements saying they won't make games exclusive doesn't mean they'll abide by those public statements.
People swear microsoft always intended to keep COD multiplat, but they're full of shyt. I been said they were saying the same shyt to get the Bethesda deal through regulators. Now they're under scrutiny because they've been spending too much money too fast and using PR speak to convince regulators that they aren't trying to create a monopoly.
And the scariest part is that after the activision deal, they haven't even spent half the amount they set aside for acquisitions, they can realistically buy every major 3rd party publisher and have money left over.
