Microsoft Corp (MSFT.O) has delayed the launch of its Xbox One game console in China, which had been set for release on Tuesday, but the world’s biggest software company said it would be released by the end of the year. Microsoft did not give a reason for the delay in a statement on Sunday. The delay is the latest in a series of setbacks for Microsoft in China, where it is under investigation for suspected anti-trust violations related to the Windows operating system and Microsoft Office. The Chinese government lifted a 2000 ban on gaming consoles earlier this year.
