The recent Blackout beta for Call of Duty: Black Ops 4 was so much of a success for Treyarch that the analysts at Piper Jaffray have decided to raise the sales estimate for the game.

As reported in late July, their initial estimates were that it would have sold 21.5 million units by the end of 2018. However, Piper Jaffray has now issued an updated report raising the estimate to 23.5 million units.
