I doubt that it'll have an appreciable affect on the regionals with a very junior payscale. but for places like my airline, piedmont, with a very senior pilot group i think that it will have a very detrimental affect on the already very long upgrade to captain.

But, you've always got to consider the guys at the top whom it has the greatest affect on, if they want to keep working its great for them, if not, well then they'll just go away.
