Microsoft could buy Activision Blizzard by the end of the week. Here's what that means for 'Call of Duty.'

• Microsoft is closing in on a deal to buy Activision Blizzard.
• Activision President Rob Kostich said he thinks the deal will make "Call of Duty" better.

Activision Blizzard's president thinks that Microsoft could make the "Call of Duty" franchise even better.

Microsoft is closing in on a deal to buy Activision Blizzard by October 13, pending a final sign-off from UK regulators, The Verge reported. The deal will see Microsoft acquire the gaming giant responsible for popular titles like "Call of Duty," "Overwatch," and "World of Warcraft" for $68.7 billion, the report says.

The UK Competition and Markets Authority previously blocked Microsoft's attempts to buy Activision Blizzard, causing Microsoft to reorganize the deal.

As part of that restructured deal, Microsoft would no longer purchase Activision's cloud gaming rights, which would instead be sold to Ubisoft, the developer behind the "Assassin's Creed" series. This would mean that Microsoft could not exclusively offer Activision Blizzard's games on the Microsoft-owned Xbox Cloud Gaming service.

If the deal goes through, Activision President Rob Kostich thinks "Call of Duty" will benefit from being able to use Microsoft's wealth of development resources.

"Being able to tap into Microsoft's technology and suite of tools would benefit our teams to create even greater, more immersive experiences for our players," Kostich told Games Beat. "Ultimately, it's about bringing our development team's creative visions to life in this hyper-competitive environment."

Kostich told the outlet that he thinks the merger is an "extraordinary opportunity" for the company but added that "we still need to allow the regulatory process to run its course."

"As we've said previously, this deal is good for the industry and will bring more games to more players," Kostich told Games Beat.

Microsoft declined to comment when reached by Insider on Sunday. Activision Blizzard did not immediately return a request for comment from Insider.
