Looking for a PS4? "Be patient" Sony says

PlayStation executive Shuhei Yoshida has some advice for shoppers hunting for the still-hard-to-find PlayStation 4. "Be patient," the Worldwide Studios boss told a fan on Twitter today who mentioned that Xbox One units are readily available at numerous outlets.

Indeed, while the Xbox One is available through major retailers like GameStop and Amazon, the PS4 remains sold out through those channels. Sony said last month that the PS4 would remain "supply-challenged" for the balance of 2013, with new shipments becoming available in January and February 2014.

A fan also asked Yoshida if he could say how many PS4s have been sold worldwide as of January 2, to which he responded, "I do not know." SCEA CEO Jack Tretton went on record in December to say Sony would sell 3 million PS4 units by the end of calendar 2013, but that time has come and gone without a new sales update from Sony.

Officially, the PS4 and Xbox One are neck-and-neck, each having sold more than 2 million units since their launches in November. Sony expects to sell 5 million PS4 consoles by the end of its fiscal year in March 2014. In the United Kingdom, the PS4 outsold the Xbox One in 2013 by a substantial margin, according to data from research group Gfk Chart-Track.
