as for future upgrades/movement at Colgan or any other regional for that matter minus maybe expressjet and Eagle... I was at a job fair less than 2 years ago in ATL and a few regionals (the names escape me) were offering classes to 500hr guys upon interviewing them in the hotel! I even interviewed for 2 street captain positions around the same time - Now no movement... I suspect in a year or two things may be different despite the economy.
The flood gates will reopen... and regionals like Colgan who have a ton of young capts with PIC turbine time will rush to the majors and upgrades will sky rocket again... I've lived to see 2 cycles so far...

In the mean time just enjoy what your doing! Like I said- my 4 years as a pilot I never "worked" a day. (omitting recurrent of course)
