A pair of purported concept sketches for PlayStation Orbis - the rumoured codename for Sony's next home console - show gamers interacting with what looks like a PlayStation Eye device.
As spotted by Kotaku, two images appeared on the website of design firm Coques Design labelled "Illustrations & Sketches for new PlayStation Orbis features".
Both showed what appeared to be a motion-sensing camera on top of a TV and a player selecting tracks for an on-screen dance game via what looks like a smartphone.
The images were quickly taken down, with Coques so far declining to comment.
Sony Music is listed as one of the firm's clients on its website.
