Gamers will be able to get their hands on the new console from 29 November.
The PS4 already has a million pre-orders, according to Sony, but gaming experts said the later than expected launch date could play into the hands of main rival Microsoft, which has yet to announce when its Xbox One will go on sale.
“From Microsoft’s point of view it looks pretty good,” said Seth Barton of technology website Expert Reviews. “I think Microsoft will probably want to get in first and launch a week or two before Sony, just to claw back a bit of an edge.
“If you’ve got a PS4 pre-order you will definitely get one for Christmas, but if you haven’t, then that boat has sailed and you haven’t got a hope of getting one, and then you might end up getting a Microsoft instead.”
He said PlayStation 4’s pre-order figure was “pretty impressive”. He added: “Sony couldn’t have announced it any later – you’re unlikely to get a launch in December. It’s quite possible both consoles will sell out before Christmas and you won’t be able to get either of them.”
