Not only did they present the logo, but they had some of the weapons from the movie to show off, and comicbook.com snapped some pictures. EDIT: Found better pictures. Click for full resolution.
Doomhammer A savage orc weapon unleashed in the name of the Horde
Dragon Sword This gleaming blade is wielded in the name of the Alliance
Lion Shield Symbol of the strength of Azeroth
I don't know WTF is up with that sword design. I mean the blade, not the hilt. The hilt is amazing.
