Updated, June 22: Sony has confirmed the arrival of the 1TB PlayStation 4. It currently only has a European launch date (July 15), but given the FCC filings (below) it will presumably also come to the US this summer.

Original story

The PlayStation 4 seems set for its first major hardware redesign, according to testing documents filed by Sony and published by the FCC.

PlayStation 4 Model No. CUH-1215B will sport a 1TB hard drive as standard equipment as opposed to the 500GB hard drive on the CUH-1215A, according to documents unearthed by DualShockers. That would be the first official storage capacity increase for the PS4, but users have been able to easily upgrade the system's default storage with any serial ATA 2.5" hard drive since launch. Microsoft started offering an Xbox One with a 1TB hard drive last year.

In addition to the upgraded hard drive, the new PS4 models also feature a 230W 2.3-0.95A power supply, compared to the 250W 2.5-1.15A power supply on the last model. That should help a bit with the system's active power draw, which can consume up to 150W in the middle of an intense game. The new design is also slightly lighter than the existing PS4, down from 2.8 kg to 2.5 kg, according to the documents.

The PS4 actually saw a very minor redesign to its innards last year. The original CUH-10XXA model was replaced with a new CUH-11XXA model that sported a slightly different Wi-Fi antenna and more efficient WLAN and Bluetooth components.
