PlayStation UK boss Fergal Gara told Eurogamer that Sony expects the systems to be bundled together for under £500.
"It'll come to market in a few different shapes and guises," he said. "You may walk in and get a great deal on 'buy a Vita when bought with' type deal. So if you buy a PS4 you can get a Vita for X. And others will say, well here's the Ultimate Bundle and you get all those bits in it.
"But as a base price point, in other words for the two consoles, we expect the gamer to be able to pick that up for under £500. It's not a hard bundle pack at this point in time. It's us working with the retailer to effectively deliver a soft bundle."
PS4 launched in North America on November 15 ahead of this Friday's European and Latin American PS4 release date of November 29.
