PlayStation 3 motion controller Move has sold around 1.5 million units in Europe, according to Sony's Andrew House.
Speaking to Bloomberg, the head of Sony Europe said the company was looking to increase production of the controller, which launched in the region on September 19.
Move has seen "very significant sales in the first month since launch, somewhere in the region of 1.5 million units for the new controller across just Europe," according to House.
"The initial sales response has been so far in excess of our initial plan that we'll probably be looking at accelerating production."
He also said that Sony is expecting to beat worldwide sales targets of 15 million PlayStation 3 units for the full year, despite the slow down in the overall market.
"Sales have been significantly up year-on-year in a market that has been overall slightly down," offered House.
"We have lots of confidence in our ability to hit our profitability target this year," he added. "But currency movements present significant challenges" he said, referring to the appreciation of the yen.
