On the heels of disappointing sales and price cuts in Europe and Australia, Seamus Blackley, chief technology officer for Microsoft's Xbox gaming console, has left the company, a Microsoft spokeswoman confirmed Monday. Blackley is leaving Microsoft to pursue other opportunities, the spokeswoman said, but she declined to provide more detail. She also declined to say whether Blackley's resignation was effective immediately. The Redmond, Washington, company has not yet named a replacement. Blackley's departure comes after two weeks of difficult news about the Xbox. The company said that sales for the game console would probably be between 3.5 million and 4 million units worldwide for its fiscal year – which ends June 30 – down from the 4.5 million to 6 million systems it had previously expected to sell. Microsoft also cut Xbox prices in both Europe and Australia to help boost weak sales in those regions. Blackley's departure has "absolutely" nothing to do with disappointing numbers, the spokeswoman said. To the contrary, Microsoft feels good about the console's future, which the spokeswoman characterized as being "off to a fantastic start."
