Airbus says reengining the A319, A320 and A321 with new PW GTF's and new GE LEAPX will cost them around E1 Billion. Fuel saving should be around 15% or give payload / range. It will be significantly quieter and cleaner (NOx) too.
The NEO combined with the CSeries and some other entrants causes Boeing a serious headache IMO. What new engine technology will be available in 2019? It probably isn't coming from Pratt or GE. Maybe it's there when Airbus comes up with their new NB, 4-5 years later.
The Boeing backlog (2000+ 737s) runs in to 2015-2016. Will a new CFM powered 737 be a good investment for any airline after .. 2014? with clearly better competitors entering service?
