I don't think that PXD will settle. The Trust legal team won't give them an option that they can live with.
I agree with you that this will go to trial or very close to it.
Sun Tzu points out that underestimating your enemy is a grave mistake. "Pretend inferiority and encourage his arrogance."
PXD has hired a talented legal team. They are willing to spend serious money on defending this case. I don't know what the outcome will be. I have bought units in hopes of a sucessful outcome. There will be heartache before this is over, even if it ends in our favor.
