Update: Looks like this may be another fake thrown into the game. A nearly-identical mockup was posted on Twitter not long ago, so this could just be another elaborate hoax.

Mockup (by Twitter user Daniel UY):

We've been hearing rumors of the Galaxy Note 2 for several weeks now, and a pretty believable image of the device has now made its way onto the net ahead of Samsung's August 29th event where we fully expect the device to be announced.

What makes this picture all the more believable is the fact that a previously leaked image of the purported Note 2 digitizer perfectly matches up with what we're seeing today. According to the previous leak, as well as several rumors, the display should come in at a whopping 5.5 inches; however, the device is said to keep a similar size to its predecessor thanks to the razor-thin bezel.

While other details are scarce at the moment, the Note 2 is expected to have most of the same innards as the Galaxy S III, which includes a quad-core Exynos processor (Snapdragon S4 in some regions), 2GB RAM, and Android 4.0.
