repeatedly, that Sony intends to unveil a 40GB PlayStation 3. While this may not be proof, a recent FCC exhibit from Sony reveals a PS3 with a new model number, CECHG01.
All the apparent specifications -- WiFi, Bluetooth, CPU, etc. -- are identical to the other PS3 models. As Engadget points out, Sony likes to use a new model number for every hard drive tier. Whether or not this is an increase or decrease in HDD capacity remains to be seen, but it does look like Sony is prepared to unveil another choice for potential PS3 owners.
