A new trailer for the next entry in the ultra-popular vampire/werewolf series The Twilight Saga: Eclipse premiered this morning on Oprah’s talk show and we have it here for your viewing pleasure.

Eclipse, like its predecessors Twilight and New Moon, is based off the book of the same name by author Stephenie Meyer and was adapted for the screen by Melissa Rosenberg.  However, David Slade (30 Days of Night) will be holding the directorial reins this time around and – if the new Eclipse trailer is any indication – has raised the action quotient significantly from the previous Twilight films.

Have a look for yourselves:

The string of murders mentioned in the trailer is the work of an army of vampires led by Victoria (played now by Bryce Dallas Howard, replacing Rachelle Lefevre from the first two films), a vampire whose equally-undead lover, James, was killed by Edward (Robert Pattinson) in Twilight.  Victoria is now on a quest for vengeance against both Edward and his mortal lover, Bella (Kristen Stewart).

So – as you likely picked up from the trailer – the werewolves are recruited for battle against the army of evil vampires wrecking havoc on Seattle, Bella faces her impending graduation from high school, and the Volturi (from New Moon) are in town and wondering why Bella hasn’t been turned into a vampire yet.

Of course, all of this other activity just complicates Bella’s attempt to choose between an immortal life with her glitters-in-the-sun true love, Edward, and her occasionally hairy, unwaveringly loyal best friend, Jacob (Taylor Lautner).

And you thought Meryl Streep had it rough in 'It's Complicated.'

Eclipse looks like it will have its fair share of scenes with CGI-beasties and vamps duking it out – not to mention an overall darker visual style and faster, more action-driven pacing than either of the first two Twilight films.

Of course, let’s not forget that the Bella-Edward-Jacob love triangle will still be the centerpiece around which the rest of the plot revolves – something that I suspect the designer of this new trailer was going out of their way not to emphasize.

So what do you Twilight fans out there think?  Are you even more pumped for Eclipse than before?

The Twilight Saga: Eclipse hits theaters on June 30, 2010.
