Breaking Dawn.. Movie? Or no?

No one has decided on if Breaking Dawn is going to be an actual movie or not. I know all the fans would die for it to be, but there are some things about the movie that make it a little harder to make than Twilight, New Moon and Eclipse. (Spoilers Ahead) The Twilight Examiner goes to investigate:

"We also know that Summit Entertainment has taken The Twilight Saga: Breaking Dawn as an “optioned property,” which, basically, means that they have the choice whether to make the film or not - and they haven’t decided at this point. We also know that Robert Pattinson was quoted to say on the Red Carpet of the Oscar’s this March that Breaking Dawn would, indeed, be made as well (video below - saying “and Breaking Dawn’s gonna be done at some point as well, so yeah…”)."

There is an issue with casting Resnesmee that makes it harder to

 make. Babys don't just have a full set of teeth and can grow at rapid speed. She also can talk like a mature adult and jump 8 feet in the air. If anyone can find me a baby that can do this, WOW. Haha.

Another issue is that it would be too long to capture the actual book. And also the birth scene would turn it to rated R. SPOILERS -

“When she gives birth, Edward rips open Bella’s stomach with his teeth to get the baby out.

It’s a bloody and gruesome birth. And what does the little bugger do once she’s out? Sinks her half-vampire teeth into mom’s chest, that’s what. What follows is an equally bloody and gruesome transformation of our teenage heroine into a vampire. How any of the birth scene gets magically transformed into a PG-13 moment is anyone’s guess.”

I mean I'm 17 so this doesn't really affect me but, fans are going to be pissed who can't go see this movie. They are going to have to trail their parents along. Also they say that the woman playing Heidi, Noot Seear, has signed onto doing the next 3 movies. As far as I know Heidi wasn't in Eclispe and Breaking Dawn?

Who knows what is going to happen, all I know is that they need to figure out a way to make this movie or fans are going to be quite upset..
