Great teaser. There's a few minor things they're doing with the film that kind of irk me (taking "Episode 7" out of the title--I really hope they leave the opening text scroll alone at the beginning of the film; the new lightsaber--of which rumor says that ALL the lightsabers in the new Trilogy will look like this, except Luke Skywalker's), but all in all, it looks pretty incredible. The shot of the X-Wings screaming across the surface of the lake and the Millennium Falcon inverted-camera shot across the desert of Tatooine(?) with the opposite direction TIE Fighters shooting at him made me grin like an idiot!
Looks like many of the rumors are actually proving to be true. Looking forward to seeing the film...it's going to be a LONG year to wait!
