As I have stated in a prior post, I believe they will file as many as 10 per quarter.
They need to get settlements on the original 8 with a substantial amount in the piggy bank, then watch how they will speed up the process.
I don't think DM wants to drag this out beyond a 4-5 year time frame. If they get a number of settlement by discussions, without filing the suits, then the entire process may take less time then stated above. This is a possibility.
Think of how this would benefit edig and their long term business plan .
