New Sony Ericsson bluetooth car speakerphone found at FCC

This is a new accessory approved by the FCC today along with the P1 smartphone. Is this a sign of an announcement soon (maybe the June 14th date is definite?)? Now we have two accessories, the other being the bluetooth headset DS200. I am not really into car handsfree since I never talk on the phone when I am driving. This handsfree does look smaller than the HCB120. If I am not mistaken this will be called the HCB100 placing it below the HCB120.
