Sony's PlayStation 4 recently passed certification through the Federal Communications Commission, according to documents on the FCC's website.
The FCC regulates communications via radio, television and more; with its certification, the system is approved for U.S. sale. The documents reveal little about the console other than a few technical details, such as its size, weight and "maximum clock frequency" of 2.75GHz.
The PS4 dev kit was approved by the FCC about a week ago.
The PlayStation 4 is expected to launch this holiday for $399. Last week, Sony confirmed that the console will support PlayStation 3 wireless headsets.
