First 'The Twilight Saga: Eclipse' teaser revealed

Capture from the 'Eclipse' teaser

The first ten second teaser for The Twilight Saga: Eclipse has finally been unveiled!
In the clip, two moments of the film are shown. The first is an exchange between "Bella" (Kristen Stewart) and "Edward" (Robert Pattinson).
"I know the consequences of the decision you're making," he says to her.
The second is one involving "Jacob" (Taylor Lautner).
"I'm going to fight for you . . . 'til your heart stops beating," he says.
The first exchange could be either a portion of the proposal sequence or of a conversation about Bella's decision to transform into a vampire, while the second is almost certainly a portion of the conversation that Bella and Jacob have about him protecting her despite his disagreement with her wishes.
