"Faced with weaker competition," Sony continues, "Microsoft would be able to: increase console and game prices for Xbox users (including those that had switched from PlayStation); increase the price of Game Pass; and reduce innovation and quality."We also know that an existing deal between Sony and Activision will continue to keep the franchise off Game Pass for several years as well, even if Microsoft is clearly keen to bring Activision Blizzard games to the service.Just to pull something out of the air, it could take pointers from the myriad PlayStation-exclusive content in Modern Warfare 2, which was the biggest Call of Duty launch ever on PlayStation.This is presumably why PlayStation Plus gets several sections in Sony's response, with the company claiming that its subscription service would, as a result of this deal, be excluded from Call of Duty opportunities and consequently weakened.Sony claims this would trickle down to independent developers as well, who would "likely receive worse terms for their content from Microsoft or even be required to promise exclusivity" due to the "weakened negotiating position" of PlayStation and PS Plus."
