My take:

1 - We might have a TA soon. If not, don't expect one for quite some time.

2 - DALPA is prepping us for some type of scope concession. Why else emphasis the ratio of mainline vs. non-mainline pilot block hours?

3 - They want to act fast before US Airways snags American and that's why the TA will be soon, or not at all.

That summary is worth what you paid for it .
