Sony announced that the S1 tablet device will be called the Sony Tablet S with a 9.4-inch multi-touch display, will have a Nvidia Tegra 2 processor, be 4G and WiFi-compatible and come in 16GB and 32GB versions for $499 and $599. The S2 will be called the Tablet P, with two 5.5-inch touchscreens, dual Tegra 2 processors; no price has been announced, but it is expected to release later in the year.

“These devices truly represent the best of everything Sony has to offer,” said Mike Lucas, senior vice president of Sony Electronics’ Networked Technology and Services Division. “From hardware to software and services, Sony Tablet devices embody all our innovations rolled into one.”

Both tablet devices are PlayStation Certified, meaning they can run PSOne titles. These tablets will have to use touch screen-integration, however, since there aren’t buttons for gameplay like the Xperia Play.
