It looks like the FCC has spilled the beans on yet another top secret product. Sling Media has received approval for an update to its Slingbox Pro place-shifting device.

While the new model carries the Slingbox Pro name, it doesn't include an HDMI port, making it a cut below the existing version. But it does support S-video, coaxial, and RCA inputs and outputs as well as an ethernet jack. TG Daily speculates that this feature set could make the new box a replacement for the Slingbox A/V.

No word on pricing or availability, and a Slingbox rep would neither confirm nor deny this device's existence, other than to say that the company continues to develop new products. But thanks to the FCC, we do have a whole slew of pictures after the jump.

Oh, and did we mention that the product manual is available from the FCC's site as well? But why struggle to navigate the FCC's web pages when you can just read through the manual here.
