The world's most efficient regional jet. Available in a 28 pax + cargo, 50 pax model in the same airframe and a 68-80 seater (possibly 2 class).
Niether Airbus or Boeing is much interested in the RJ
market. Airbus got close with the AC
-15X that was to be partnered with a Chinese firm, but nothing happend with that.
Boeing will probably turn to a complete 737 replacement, not another NG
program. My prediction is a 130, 160, 190 seat aircraft with 2+2+2 narrow-widebody seating, maybe a hybrid tube-wing/BWB profile, ultra-high bypass engines, and all-composite construction. WN
will probably dictate most of the requirements for this aircraft and their launch order alone will practically make them risk sharing partners (100+ to replace 737-300 fleet), with an EOS of 2015. Hopefully Boeing will keep this project in the US of A....
Something I forgot to add- GE, RR, and PW will fight like dogs to get on this aircraft. The CFM56 and IAE V2500 will probably not be contenders, and an all-new core will probably be in order. If PW doesn't get on this airframe it will probably be the end of their commercial market. Even though the 737 is exclusive with the CFM56, I don't see why the 737-Replacement can't have a swappable pylon and thus more than one engine supplier.
