Sony's Response to Microsoft's Activision Blizzard Buyout: Necessary or Not?

Following Microsoft's $69 billion purchase of Activision Blizzard, the question arises whether Sony needs to respond with its own acquisitions. Sony Interactive Entertainment business boss Eric Lempel stated that while PlayStation is still open to partnerships, their focus remains on great content. Sony has engaged in mergers and acquisitions in the past decade, such as buying Insomniac after partnering with them as a 'second-party' studio. As the industry speculates on Sony's next moves, the question also arises whether other big video game companies will be targeted by Microsoft.
