Grand Theft Auto 5 sales have likely surpassed 15 million units worldwide, according to Cowen & Company analyst Doug Creutz.
He wrote in a research note sent to investors this morning: "Based on the $1B three-day figure Take-Two disclosed, we believe the game has already sold through at least 15MM units.
"For a game to sell 60% of its first year units in just three days would be abnormally high; we estimate that Call of Duty sells about 45-50% of its first year units in its first week at retail.
"However, for now we are assuming that GTA V sales will be extremely front-loaded due to high gamer anticipation, and will also have a shorter sales tail given the launch of next-gen consoles in November."
Creutz expects the game to sell 25 million copies in its first year of availability.
Released last Tuesday, Grand Theft Auto 5 is the UK's fastest selling game ever, moving more copies in its first week than the total launch week sales of all previous series entries combined. Launch week sales were 2.4 times greater than GTA 4's and bettered the launch week of Call of Duty: Black Ops, the UK's previous record holder, by almost 250,000 copies.
In our GTA 5 review, we said Rockstar's latest is "sprawling, thrilling, and beautiful." We concluded by labelling it "the best Grand Theft Auto yet."
