No, the point of all the large RJs was primarily to replace the uneconomic 44-/50-seat RJs, just as Delta is doing. Three CRJ700s is a perfect replacement for four EMB145s. And yes, there will be plenty of them to do just that when combined with the growth at mainline, and the elimination of marginal 50-seat markets - again, just like Delta is doing.
AA clearly has essentially the exact same strategy as Delta for drawing down small jet flying and upgauging to larger RJs or smaller mainline - so there should be no need to write endless diatribes tearing this strategy down.
