Regulators scrutinize Microsoft's $69B Activision buyout amid Xbox's console war loss and exclusive game controversy.

The US Federal Trade Commission has argued in court for a preliminary injunction to block Microsoft's acquisition of Activision Blizzard, citing concerns that the deal would harm competition in the videogame industry. The FTC claims that the merger would give Microsoft's Xbox console exclusive access to Activision games, leaving Nintendo and Sony's PlayStation out in the cold. Microsoft argues that the deal would benefit gamers and gaming companies alike and has offered to sign a legally binding consent decree with the FTC to provide "Call of Duty" games to rivals for a decade. The hearing is scheduled to proceed through June 29.
