The new model will have the 0ption of a 1 Terrabyte hard drive in the console. This model will most likely be announced this year before Christmas. Perhaps during E3 press conference of Sony. Fans have been speculating that there will be a price drop, but it seems that they want to make the hard drive bigger.
The new models are called: CUH-12XXA and CUH-12XXB. They are both certified by the FCC as well. The new models aren't total redesigns, but small improvements on the original design. The biggest change is probably that the new model will use 230W instead of 250W on the original.
