It seems like just yesterday that Twihard Nation was forced to choose between Team Edward and Team Jacob for the release of 'New Moon', the second film in the massively popular 'Twilight' saga.

Less than a year later, they'll have to choose sides again.

As we see in this teaser trailer for the upcoming 'Twilight: Eclipse', the Cullens and Blacks remain in supernatural, Hatfiled/McCoy mode over the fate of Kristen Stewart's Bella Swan. Edward (Robert Pattinson) struggles with mounting pressure to transform her into a vampire, while heartbroken Jacob (Taylor Lautner) tries, shirtless of course, to convince Bella that werewolf loving is the way to go.

Watch the trailer after the jump.
