Sony Computer Entertainment has submitted what appear to be plans for a new PS3 model to the Federal Communications Commission (FCC), an independent US government agency which regulates communications by radio, television, wire, satellite and cable.
As spotted by NeoGAF users, Sony supplied a sample of a "Computer Entertainment System" model number CECH-4001x (pictured) - an upgrade from the current 3000 series (second picture) - to the FCC for testing on March 9, 2012.
The smaller, more energy efficient and cheaper PS3 Slim was announced at Gamescom back in August 2009, and recently rumours have been circulating that Sony intends to release a new model designed to take advantage of late adopters.
Asked last month about the possibility of another PS3 hardware revision, Sony Worldwide Studios boss Shuhei Yoshida didn't rule out the possibility.
"We haven't announced anything new on PS3 in terms of hardware revisions," he said. "We should never say never - hardware guys are always looking at ways to make things cheaper, smaller."
