Apparently, the European Union (EU) plans to file charges against Microsoft in connection with its acquisition of Activision Blizzard.

Sources familiar with the matter told Reuters that Microsoft is likely to receive an EU antitrust warning in connection with its $68.7 billion acquisition of the publisher of Call of Duty and World of Warcraft, adding to a growing list of organizations expressing concern over the deal.

The charges are expected to be submitted in the coming weeks, although Microsoft has apparently maintained that confident in the success of the deal. “We continue to work with the European Commission to resolve any issues that arise in the market,” she said. “Our goal is to bring more games to more people, and this deal will further that goal.”

The deal has also come under scrutiny from several US senators, New York City and the US Department of Justice, with the Federal Trade Commission finally filing a lawsuit to block the deal in December.

The UK Markets and Competition Authority was also forced to expand its investigation into the deal earlier this month due to its complexity and lengthy responses provided by both Microsoft and Sony.

In one of these responses, posted at the beginning of October, Microsoft basically claimed that PlayStation is too big to fail even if it did acquire these games, and that Sony already has many more exclusives anyway.
