Hot on the heels of the appearance of a white version of AT&T's LG Optimus G Pro, another unannounced device that'll soon grace the big blue carrier's shelves has leaked out.

This time we're looking at the Samsung Galaxy Mega 6.3, a device that's been rumored as being AT&T-bound in the past. As you can see in the image shared by @evleaks, this SGH-I527 "Melius" variant of the Galaxy Mega 6.3 looks fairly similar to the international model that launched earlier this year, save for the AT&T branding in its status bar and below its rear camera.

As its name suggests, the Samsung Galaxy Mega 6.3 features a display that's 6.3 inches in size. The screen is a Super Clear LCD panel that sports a resolution of 1280x720. The Galaxy Mega 6.3's spec list also includes a 1.7GHz dual-core processor, 8-megapixel rear and 1.9-megapixel front cameras, 1.5GB RAM, microSD card slot and a 3,200mAh battery. Powering the pocket-stretching handset is Android 4.2.2 beneath Samsung's custom TouchWiz user interface.

AT&T was the first U.S. carrier to launch the original 5.3-inch Samsung Galaxy Note, and it currently sells both the 5.5-inch Galaxy Note II and LG's 5.5-inch Optimus G Pro, so the carrier is no stranger to the phone/tablet hybrid category. That's why it's not entirely surprising to see that the supersized Galaxy Mega 6.3 will soon find its way onto AT&T's shelves. Now we just have to wait for AT&T to come clean with its launch plans. Until then, you can check out Aaron's two-part review of the international Galaxy Mega 6.3 here and here.
