Engadget has spotted a banner at CES that spills the beans on Samsung's tablet plans. There is a huge advertisement in the South Hall of the Las Vegas Convention Center that depicts the Galaxy Note Pro and the Galaxy Tab Pro.

The Galaxy Note Pro was previously rumored as a 12.2-inch tablet, and the banner does nothing to refute that (or provide any additional information). The Tab Pro has previously been rumored as a tablet coming in 8.4- and 10.1-inch sizes. What the "Pro" moniker designates over a normal Note tablet is still a mystery. The banner gives Samsung's Knox security software a prominent location on the device's home screen, so perhaps Samsung is just pushing for the business sector with its naming choice.

Speaking of the software, if that is the home screen, the depicted software looks to be a big departure from older versions of Touchwiz. It has an app drawer icon in the lower right, as if it were a launcher, but rather than the usual grid of icons, it uses a Windows Phone-style tile layout. Some of the tiles are just pretty versions of app icons, and others are widget-based, showing inbox emails and the weather. It's also missing a status bar.

The full news behind the banner will be revealed soon—Samsung's CES press event is tomorrow at 2pm pacific, and Ars will be there to cover it.
