It's believed that the #4453-4482 batch may go to Casey Stengel to kick out the rest of the 600's to retirement over there @ CS. What will Jamaica get might be the remandier of the '96 RTS @ QV & few from LGA, FP and/or Storage.
IMO if this happened earlier (In December) they could've sent some of QV's '96 RTS back to Jamaica like #8907, #8933 etc to push the 44XX NG's to Stengel. But that's just what I think.
