On 29 November the Japanese tech giant released its PS4 across around the rest of the world, and i's now available in 32 countries including Australia.

Microsoft's Xbox One had a simultaneous worldwide launch on 22 November, and it's believed is experiencing similar sales numbers.

Microsoft has yet to release a statement for the number of Xbox Ones sold in November.

Australian PS4 sales figures are yet to be released, with the console only going on sale less than a week ago.
