If you remember, Sand Dollar Enterprise is a pseudonym used by Sony for FCC filings. Sand Dollar was used to pass the original PS3 Slim through the FCC, for example.
Sand Dollar's filing today is for the CECH-2101A 'Computer Entertainment System.' Label pics for the device confirm that this is indeed the Sony PS3, while label placement pics show a device that is the same size and shape as the PS3 Slim.
Another device, called the CECH-2101B is also identified in Sand Dollar's filing. The only difference between these two devices is the hard drive size.
