UPDATE: YES it is, if you want to find how the real Samsung GS3 look click here …
I did found on a Coreean website a leaked picture supposed to be the next generation Samsung Galaxy S3. The picture is a ad for S3, with the date 22 May 2012, London, United Kingdom
As you can see this picture is very different by the other leaked pictures, and in this one the shape of the phone is very futuristic.
