Microsoft's blockbuster $68.7 billion purchase of game maker Activision Blizzard may face a new regulatory hurdle, with a report from Politico saying the US Federal Trade Commission is "likely" to file an antitrust suit against the deal.An Activision spokesperson defended the deal, saying in a statement that it will "benefit gamers and the U.S. gaming industry, especially as we face increasingly stiff competition from abroad."FTC Chair Lina Kahn has long expressed interest in reining in tech's largest companies, which have grown to become some of the largest and most highly valued on the planet.Regulators and lawmakers across the globe have increasingly scrutinized the tech world, following a series of privacy and political scandals at Facebook and Google in particular.Longtime video game industry analyst Michael Pachter, of Wedbush Securities, responded to the story, saying he expects that the regulator would be "crushed in court" and that likely it'll strike an agreement with Microsoft "to maintain the status quo.""
