I would read through the Right of First Refusal Thread because it varies. Some people hear very quckly, others have to wait a few weeks (which ends up like feeling forever).
We just heard yesterday about our BWV add-on----it went through. Our timeline is about the same as yours. Some say the rofr people meet on Tuesdays, so you might want to call your re-sale agent today and see if he/she heard anything. Good luck!
