Two new PS4 models have been outed.
The models are CUH-1215A and CUH-1215B, with the latter including a 1TB hard drive. It appears that there will be no cosmetic changes, however the innards have been slightly altered on both units, with the power supply dropping to 230 W and 2.3-0.95 A. Both lower than the current models.
Here's the certification PDF.
