Delta has more or less announced that they are doing away with most of their regional flying and it is moving to mainline. That will mean much less flying at the regionals. The time frame for the arrival of the C series at Delta coincide with the end of the retention bonus at Endeavor. That will likely mean that those at Endeavor that do not go to Delta will be looking elsewhere for a job, or be stuck with what flying is left making very little money.
