Microsoft’s Call of Duty offer, according to Sony, was “inadequate on many levels.”

Microsoft may need to provide Sony additional assurances about the future of Call of Duty, particularly while competition concerns over the franchise are being investigated by authorities in the UK, Europe, the US, and elsewhere. Last week, the UK’s Competition and Markets Authority (CMA) said that it will conduct a more thorough investigation into Microsoft’s Activision Blizzard acquisition. The CMA has launched a Phase 2 inquiry, in which it will create an independent panel to evaluate whether Microsoft’s ownership over games like Call of Duty and World of Warcraft is harming competitors.
