According to the leaked specs, the Galaxy Tab S will run Android 4.4 Kitkat on an 8-core Exynos 5 chip, combining four 1.9GHz cores and four 1.3GHz cores as well as a 6-core 533MHz Mali-T628 GPU.
There's going to be two models, one with a 10.5" screen and another with an 8.4" screen. They will have 3GB RAM, an 8MP camera, and a 2.1 MP camera. And as we can see in the photos below, the rear camera will be equipped with an LED flash.
In terms of connectivity, the Galaxy Tab S will offer Wifi, Bluetooth, Glonass, GPS, and an IR blaster. There will also be models with LTE, but current reports say there won't be a 3G model.
And as you can see in the photos, the Tab S 10.5 looks like the many other 10" and larger Android tablets from Samsung. In fact, I am not sure I could tell the difference between this tablet and any of the other models. The lack of a slot for the stylus tells us this is not a Galaxy Note, but that (and the flash on the rear camera) is about its only distinguishing feature.
One of the Tab S line's other distinguishing features is not obvious in the photos, and that is the fingerprint scanner. Both models will reportedly have a scanner integrated into the home button (just like Apple added a fingerprint scanner to the iPhone 5S).
The leaked specs for the Tab S line tell us that we are looking at a premium line of tablets, with prices expected to be between the Galaxy Note and Galaxy Tab Pro lines. There is no official word on when this tablet will be available.
