Sony's PlayStation 4 was only released a week ago, but retailer GameStop has already sold out of the video game console.

GameStop's PS4 launch stock is officially gone. As a result, 2.3 million hopefuls are now on GameStop's first-to-know list, Tony Bartel, GameStop president, told GameSpot today during an earnings call. According to Bartel, that high number of PS4 owner wannabes "indicates a continued demand for months to come."

It has not yet been determined when GameStop will replenish its PS4 stock. The video game retailer has not revealed how many PS4s it has sold for "competitive reasons."

Microsoft's Xbox One was released Friday, and based on a survey GameStop PowerUp Rewards members, demand for the system will also be high. In the survey, two-thirds of members said they would purchase a PS4 or an Xbox One within the next year.

Although one million PS4s sold in the United States and Canda within the first 24 hours of its release, Andrew House, Sony Computer Entertainment CEO, says there will be enough PS4s to go around this holiday season.

"[This is] the first platform launch that I've ever been involved with where we've had such a good production ramp up and a good sense of supply," House, said on Nov. 14. "I think that we will be in good supply in the countries that we've launched in."

Jack Tretton, Sony Computer Entertainment CEO, previously stated that Sony is "very comfortable" with analysts' sales estimate of 3 million units by the end of December.

House expects to sell five million PS4s by March 31, 2014.

Sony will release the PS4 in Europe on Nov. 29. By the time the holidays come around, the video game console will be available in 32 countries.
