The research found that 600,000 Australians (aged 14 and over) are intending to purchase a PS4 within the next twelve months compared to 325,000 for the Xbox One.
The survey also revealed that 8 per cent of current console owners are planning on buying the PS4 compared to 4 per cent for the new Xbox.
Finally, the Roy Morgan data saw a higher propensity for brand loyalty on Sony's consoles: 17 per cent of PS3 users intend to buy the new version within the next 12 months; only 9 per cent of Xbox 360 owners plan to buy the Xbox One.
Microsoft's Xbox One lands on 22 November, with the PlayStation 4 coming a week later on 29 November. Locally, the prices are pretty identical: you'll pay AU$599 for the Xbox One and AU$549 for the PS4.
