Samsung Galaxy S3 leaked by Samsung?

A mysterious-lookin' mobile has popped up in a Samsung promotional video -- could the South Korean tech giant have accidentally leaked the fabled Galaxy S3?

The video, spotted by Italian blog Android HD, rounds up the best bits of the company's CES press conference in only 10 minutes (so many precious memories -- we'll never know how they managed to edit that one down). It shows the slim, unidentified phone being used by three on-trend youths to remotely control a Samsung digital camera.

But is it the S3? It looks extremely thin, with a curved back and a wider edge-to-edge display. In other words, it sounds exactly like the iPhone 5 that was supposed to arrive in the summer but never materialised.

But could it be a photoshopped Galaxy Note? Possibly. The size doesn't seem to make sense, but the following shot clearly shows a Galaxy S2 -- perhaps the mobile on-screen at that moment is just a render of something that looks phone-like.

That said, it's unusual for companies to miss a chance to show off their wares in promotional videos.

Whether or not this video shows the actual S3 of legend, it's certainly what we're expecting the next flagship Galaxy phone to look like -- it is a shiny black rectangle, after all. We're also expecting the S3 to arrive sporting a 720p display, and possibly some 3D tech as well.

Watch the video for yourself (we've embedded it below, the pertinent section is at just after 7 minutes), and let us know what you reckon in the comments, or on our Facebook wall.
