Our first contract took 4 days and it failed. The next one took 3 weeks and it passed. Our agent said they only announce decisions at certain times of the month and evidently we hit it just before they made annoucements the first time.
When there are few resale contract sold ROFR can take as little as two weeks. Right now with the volume of resale contracts being submitted to Disney ROFR is taking almost exactly 30 days.
I wish I had better news for all the buyers out there.
Just because you haven't heard doesn't necessarily mean that DVD hasn't made a decision and let the seller know. I'd check with your agent if one is involved and ask they talk to the seller to see if they've heard anything, assuming you haven't gone this route already.
