The manual, posted at Korean site Seeko, doesn't give too much away. The image shows a form factor very similar to that of the Galaxy Note 10.1, highlights being a micro HDMI output, rear camera, proprietary connector (boo) and no microSD (boo).
The screen is rumoured to be running at 2560x1600 driven by a Tegra3 processor, but I imagine we'll find out more next week. It's gonna be crazy!
