Microsoft has announced that it is to double shipments of its Xbox 360 video-game console, in order to take advantage of a delay in Sony's PS3 launch. And after all - why not? They would be fools not to. The PS3 delay is not doing Sony any favours.

Two to three times as many Xbox 360 machines will be sent to retailers beginning this week, Redmond, Washington-based Microsoft said today in a statement. Microsoft, which ranks second to Sony in the $28.5 billion video-game industry, accelerated production by adding Celestica Inc. as a third manufacturer.
