The 737-900ERs are intended to replace older 752s (including the 75Ns), A320s, and domestic 763s.

Here is to hoping that one of the first few upsizes when the 717s enter service (and the other a/c shuffle around in the system) is the plane doing the rotation which includes the 5pm-ish flight from IAD/Dulles to DTW. That 5pm IAD-DTW CRJ flight seems to always be full with a terrible stuffy cabin.
