Xbox One passed FCC certification "earlier this summer before PS4", Microsoft's Larry Hryb has revealed, suggesting that the console had been further along in the production cycle than Sony's platform.

The FCC tests electrical equipment for electromagnetic interference before approving the device for release in the US, with document's discovered on the organisations website revealing that PlayStation 4 passed certification around July 22.

At the time of their discovery, some suggested that the news meant that PlayStation 4 was further ahead in its development cycle than Xbox One.

But according to Microsoft, that's not the case.

"We got FCC approval earlier this summer before PS4," Hryb wrote on Reddit, in response to fans discussing the console's manufacturing process.

Sony announced a release date for PlayStation 4 last week, confirming a November 29 launch in the UK. Xbox One, meanwhile, launches at some point in November.
