Your info regarding the flow in its current form is accurate. I'd only add that it gets renegotiated if CP is sold again. As far as Delta hiring there is a lot of conflicting information out there - much of which was discussed thoroughly in this thread:

About 75% of the CP group is still eligible, some of them are getting hired elsewhere first. The most recent upgrades have been FOs for 3+ years. Considering nearly all of us are prior 121 the true upgrade time for most people is much higher.
