Sony today revealed the official names and launch plans for their tablets codenamed S1 and S2. Sony S1 will now be called Sony Tablet S and the Sony S2 will be called Sony Tablet P. Both the devices will run on Android, Android 3.1 on Sony Tablet S and Sony Tablet P will come with Android 3.2. Sony describes both the tablets as follows:

Available for pre-sale today and on shelves next month, the Sony Tablet S device is optimized for rich media entertainment on its 9.4-inch touchscreen display. With a powerful NVIDIA Tegra 2 mobile processor, the Sony Tablet S device lets you enjoy the web as well as your favorite content and applications on its large, high-resolution screen. Weighing in at just about 1.33 lbs., its unique asymmetric design allows for hours of comfortable use and built-in Wi-Fi compatibility means Internet connectivity virtually anywhere there’s a hotspot.

Available later this year, the Sony Tablet P device is ideal for mobile communication and entertainment. With its innovative folding design, two 5.5-inch displays and weight at about 0.83 lbs., it can easily fit into a pocket, purse or backpack. It features the same NVIDIA Tegra 2 mobile processor and is both Wi-Fi compatible and 4G capable exclusively on AT&T’s mobile broadband network, offering users access to digital content including videos, games, and e-mail, while on the go, nearly anytime.

Sony Tablet S is available in 16GB and 32GB versions priced $499 and $599, and is available now on Amazon for pre-order. AT&T will announce Sony Tablet P’s pricing and launch date later this year. Check out the unboxing video of Tablet S posted by Sony.
