Sony filings with the Federal Communications Commission )FCC) seems to suggest two new PS4 models are on the way.
The documents filed with the FCC show two new PS4 models, CUH-1215A and CUH-1215B.
Most interesting to gamers might be the CUH-1215B model, which according to the product description of the submitted documents, shows that this PS4 model will come with 1TB storage, finally providing gamers with something that they have asked for even before the PS4's launch.
The other new model, CUH-1215A, will have the standard 500GB hard-drive, but both new models also seems to have had significant internal improvements. The submitted product labels show that both models have a smaller power unit, down from 250 watts to 230 watts, with an associated lowering of the amperage too (2.5-1.15 amps to 2.3-0.95 amps).
The lowering of power requirements seems to suggest the use of a more efficient fabrication process, which perhaps also allows Sony to lower the cost of production (whether this translates to a price cut or not is yet to be seen). The smaller power unit also means a lighter PS4, down to 2.5 kg from 2.8, although the external dimensions of the console will remain the same, meaning these are most likely not the plans for the "slim" version of the PS4.
With E3 less than two weeks away, official confirmation of these two new PS4 models should come at that time.
