That being said, things seemed to have moved back to the "confirmed' column with the securing of Melissa Rosenberg to write the Breaking Dawn script. Rosenberg is responsible for the other 3 Twilight Saga scripts, making her a natural choice. However, the one movie or two seems to still be a sticking point. The Awful Truth hints that 2 movies are in the works. My personal preference would be 2 just to get in all the chaos of the Breaking Dawn, but others disagree and think a lot of fluff can be cut. I'll say this, if the juicy Bella & Edward scenes are cut in any way, I will be the one cutting someone. If anything, I want more. It's the payoff of 80 bazillion pages.
Adding fuel to the Breaking Dawn fire is this interview posted by Twilight Examiner of Ashley Greene saying she believes Breaking Dawn will be filmed soon, stating as we all understand, THEY CAN'T AGE! When you're already dealing with actors in their 20's for the most part, playing immortal teens...time is of the essence.
Just a side note, I seem to be incapable today of typing Breaking Dawn without mistakingly typing Braking Dawn first. That's a different story altogether now isn't it? I'm picturing something along the lines of Smokey & the Bandit featuring a street savvy but vulnerable truck driver named Dawn. Hmm...might have something there...I call dibs on that plot.
