None yet, they've only begun filming it.
The film adaptation of Breaking Dawn is currently in the process of filming.
Update 8/11/10 - Breaking Dawn will be filmed later this year but NOT in Oregon. Filming locations so far include Vancouver, BC and Louisiana. Other location possibilities include Brazil (for the Isle Esme scenes). Breaking Dawn is not being filmed at this time. As of now it is being considered as a film project, but no production has yet begun. Once the filming of Eclipse is completed the producers will either proceed with Breaking Dawn, or not depending on the profitability of the earlier films in the series.
