With E3 just 'round the corner, it's no surprise that the FCC has outed a couple of new PS3 models. Hang on...new PS3 models? Sadly it's probably not another redesign, instead looking just like new chipsets.
The PS3 models have the serial numbers of CECH-2501A and CECH-2501B, with both including 802.11b/g Wi-Fi and Bluetooth 2.0+EDR. What makes the speculation point at new chips for the two models? The fact that a couple of debug consoles have also turned up on FCC, the DECH-2500A and DECH-S2500A, which you can see in the two lower rungs on the above chart. The notes underneath say that the CECH-2501B "is similar to the tested model CECH-2501A except for HDD type," which refers to the capacity size.
