Update: Sony has clarified that the white PS4 will only be sold as a standalone product in Europe. Gamers in the United States will have to buy the Destiny bundle to get the console.
Original article: The white PS4 will be available in a bundle with shared-world shooter Destiny. However, if the game doesn't interest you, you're going to be able to buy the white console separately.
Sony Computer Entertainment Worldwide Studios president Shuhei Yoshida confirmed in an interview with GameOne (via CVG) that they're planning a standalone launch of the white PS4. It should happen by the end of 2014.
Yoshida didn't provide a specific release date. It's presumably after Destiny's debut, though. You have to figure Sony wants to give the Destiny white PS4 bundle a chance to shine.
The PS4 has only been available in black since launch. Gamers look for other colors have been forced to buy custom skins from third-party companies. It was inevitable that Sony would begin offering new colors, though. The PS3 was released in white and silver colors about a year after its debut.
There's bound to be a lot of prospective PS4 owners who want Destiny, too. Analysts are projecting the game to be fall's best-selling game. Still, the Destiny PS4 bundle will only be available in limited quantities so a standalone release of the white console ensures that everyone who wants this color can get it. It also means that gamers without any interest in shooters can buy the console on its own.
The Destiny PS4 bundle was announced at E3 2014. It includes the console, a copy of the game, a white DualShock 4 and a 30-day voucher for PlayStation Plus. PlayStation Plus is a premium membership program that provides access to online multiplayer, free games, and exclusive discounts. The bundle is priced at $449.99, which means that you're getting a $10 discount on Destiny.
Destiny will launch on September 9th. If you buy the game on its own, you can choose from several special editions.
