Boeing could offer the 737-900 as a 757 replacement (large narrowbody), and I guess the 737-800 as a medium narrowbody, and the 737-700 as the small narrowbody. Again, not very efficient, older technology.

I am discounting Embraer as they only have the EMB-170 to EMB-195 series, which aren't big enough on the top end. They might offer the EMB-195 as a DC9-50 replacement. I think that would get kinda political whether Delta would want to fly that here.

Bombardier only has the C-Series at the top end, which could be on offer, as it enters service in 2013. But, the largest one holds 120-145 seats - likely they would use a two-class configuration which would be closer to the bottom end of seating. Same thing with the politics of flying the plane here vs a regional.

I don't think the Russian (Sukhoi Superjet 100) or Chinese (ARJ-100) airplanes have a chance. Little support and I wouldn't want to buy any manufacturers first airliners.
