Sony released a new trailer teasing its S1 and S2 tablets that revealed pretty much nothing about the tablets that we didn’t already know.

The ad is the first in a series of five called “Two Will.”

It’s not as weird as the Android robot with thumbs Xperia Play spot, but apart from a glamor shot or two, it doesn’t tell us anything about the products. Let’s hope the next installments get more informative — fast.

Here’s what we do know about the tablets: Both will run Android 3.0 Honeycomb, and are WiFi and WAN compatible. They will also integrate Sony’s Qriocity music and video service and the PlayStation Suite, so users can play first-generation PlayStation titles on the devices.

The Sony S1 is a 9.7-inch wedge-shaped tablet aimed for heavy media users. The S2, a folding 5.5-inch dual-screen device, is designed for mobile use. The screens can be used together or independently, according to Sony’s official news release.

The tablets are expected in fall 2011.
