i dont think this is a very wise buiness move for bombardier..... to devlop this aircraft and market it sucessfully is going to be quite a challenge seeing that there are already several aircraft that fit in this category, 319, smaller 737, possibly some strech versions of the ERJ 170/190 if developed.....as far as branding this thing as a regional aircraft, good luck, im shure that would spur all sorts of bickering between mainline and regionals
