"I'm sure my numbers are probably a tad too optimistic..."
Not at all.
American is recalling 50 per month and has been since January. My understanding is that will continue infinitely even after the furlough and flow list is exhausted in summer 2014.
UsAirways East needs 1000+ during 2014 - 2016 (no breakdown given per year yet) just for retirements alone not including the new rest rules (though I've yet to hear even a preliminary number there so speculate as you will).
UsAirways West has 66 joining the ranks to exhaust their furlough list - haven't heard anything beyond that.
