Yep,
NB Upgrade times pretty much collapsed at Delta: Less than 1 year to M88, Less than 2 years to 717, 3 years to 737 in LAX. LAX 737 went from 17 to 3 years in a 9 month timeframe - I should know since I was on the 17 year plan.
FWIW - Although bids will continue to go junior I think the next few will mostly be more senior FOs coming in on top of these folks.
