Sony used a pseudonym, "Sand Dollar Enterprise Inc.," to obscure its PS3 slim filing at the FCC. It worked, keeping the thinner revision a perfect secret, visible in plain sight, right up until the reveal. PS3 News was first to spot the ruse, after the fact:
Sand Dollar Enterprise, Inc is represented by SCEA's General Council, Riley Russell.
This house is actually a private residence, but whomever lives here filed the documents with the FCC, most likely on the behalf of Sony, as they would be much harder to find with a different FCC ID (XCE) than that of Sony (AK8).
The filing reveals a second unit, with a 250GB hard drive.
