Activision Blizzard's Call of Duty: Black ops III launched at midnight and has received strong early reviews, Piper Jaffray analyst Michael Olson tells investors in a research note. The analyst says that while investors have cited concerns around free to play battle royale title Fortnite taking market share, he believes the latest Call of Duty is "loudly staking its claim as the top shooter title." Olson thinks his sales estimate of 23.5M units for 2018 could prove conservative given the solid reviews for the game. He maintains an Overweight rating on Activision Blizzard with an $88 price target.
