Xfire user Zilas just uploaded what we believe to be the cinematic detailing the end of the goblin starting zone Kezan. Frankly, it's amazing. There are spoilers for the end of the first part of the goblin starting experience, so be warned.
Blizzard has, once again, topped itself in terms of cinematic quality and expression outside of its general pre-rendered cinematics. Hopefully the worgen transformation movie is just as awesome.
