After all the 2012 classes start it will be around 350.

With 1400 on furlough and IMHO probably 50% ever returning (total) that's another 350 watching from the sidelines right now. I would expect a "bump" of returns with a JCBA/SLI and/or "real" UAL recalls but a good portion of those bypassing have another gig and have no problem waiting things out, particularly if they can wait a couple years and return with decent schedules once UAL has hired off the streets a while.
