The CEO of Sony Computer Entertainment has warned that PS4 demand "may well outstrip supply" following the console's well received showing at E3 this week.

The executive told the Wall Street Journal that Sony has raised internal sales projections for the console following the positive reception by consumers, although he didn't offer any specific figures.

SCE showed off the PS4 hardware for the first time on Tuesday night during its E3 press conference. It also confirmed a Christmas PS4 release date in Europe and the US and a PS4 price of £349 / €399 / $399, undercutting the Xbox One price by $100.

Additionally, Sony addressed the controversial issue of pre-owned games and always-on internet restrictions, confirming that PS4 games don't require regular online check-ins and that disc-based games can be traded or sold on. PS4 owners will however need to subscribe to PS Plus to play online multiplayer.

SCEA boss Jack Tretton also told the WSJ that GameStop executives had informed him the retailer would purchase "every single [PS4] unit" Sony can manufacture. "We're excited about the momentum," he said.

In an interview with GamesIndustry.biz, SCE UK MD Fergal Gara said the company isn't "in mass manufacture right now" but that he's confident "we'll have very significant stocks for the UK".
