Sales of the Sony PlayStation 3 console during its first full week of availability in Japan were sharply lower than those during the two days immediately following its launch, according to estimates published this week.During the seven days from Nov. 13 to 19, there were 43,378 of the consoles sold in Japan compared with 88,400 sold on Nov. 11 and 12, according to figures published by Enterbrain Friday. The company publishes local gaming magazine Famitsu, and its figures are generally regarded in the industry as reliable.\n\n\n\n\nSony PlayStation 3Another local market data supplier, Media Create, estimated sales in the first full week at 42,099 units and said they dropped further to 32,622 units in the week from Nov. 20 to 27. Media Create earlier estimated launch weekend shipments were 81,693 units.SCEI in Tokyo wouldn\u2019t comment on the estimates but said that it is continuously shipping new consoles to retailers in Japan and the United States.The sharply lower number of consoles sold is likely due to tight supply of the machines. Sony Computer Entertainment has faced problems procuring blue-laser diodes for the PlayStation 3\u2019s Blu-ray Disc drive and was forced to cut back on launch plans. It had originally planned to have 2 million consoles in Japanese, North American and European retailers for launch week, but this was reduced to 500,000 units, and the European launch was pushed back to March 2007.As a result, the consoles have been in high demand and fetching premium prices on Internet auction sites.Software sales for the PlayStation 3 have also gotten off to a slow start. Sales have been lower than expected in part because a large number of early buyers were getting the console to resell for a profit online. Enterbrain estimated that in Japan, less software than hardware was sold at launch, while in the United States,\u00a0retailer Gamestop said an average of 1.5 games were sold with each console. In comparison, the retailer reported average software sales for the Nintendo Wii were three titles per console.The highest-ranking software title for PlayStation 3 on Media Create\u2019s chart for the week of Nov. 20 to 27 was Ridge Racer 7, taking the 29 position.-Martyn Williams, IDG News Service (Tokyo Bureau)Related Links:\nHands On With Sony PlayStation 3\nExperts: Nintendo Could Beat Sony in Console War\nSony PlayStation 3, Nintendo Wii Prices Drop Online\n88K Sony PlayStation 3 Consoles Sold in JapanCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
