Not to be a downer because I really appreciate all your work Sami, but...
The B737NG is basically a re-engined B737CL, yes it has glass cockpit and so on but the A320NEO will, as the B737NG, have an updated wing, new avionics, new engines and other minor tweaks.
Hope you can get some figures from somewhere soon because the NEO will be a nice replacement for all those who operate A320s, B737s and B757s and want something slightly bigger than the CSeries.
Anyhow I support the idea of having the A320 "classic" with 15% lower fuel flow and similar seating.
