Microsoft has increased its sales estimate for its forthcoming motion-control system - Kinect, launched this week - to 5 million units this quarter, up from its previous forecast of 3 million.
That's according to the company's president of Interactive Entertainment Business, Don Mattrick, speaking in an interview with Bloomberg - making it the most successful Xbox debut to-date.
The optimism is based on a combination of pre-orders, retail demand and consumer interest, with 25,000 stores expected to sell the device in the US alone - a fifth of which will be opening at midnight for the launch.
"[Retailers] are really defining Kinect as the must-have holiday item," said Mattrick. "It means it's going to be our biggest holiday ever."
