Given the planned 2019 entry to service of the Boeing 797, assuming that the Boeing Company will proceed with its development, the three main engine companies have more than 5 years to come out with new engines that will be more efficient than the engines of the upcoming A320NEO, MS-21, Comac 919, Bombardier C300, and Mitsubishi Regional Jet.

This will give an advantage to the Boeing 797 initially, that which can be later integrated to the earlier introduced airliners.

The three main engine companies can do the following:

1. Pratt & Whitney - new turbine core for its GTF series
2. G.E. - larger fans for its LEAP-X with GEnx technology integration
3. Rolls-Royce - a new 3 spool engine with large fans

Given this scenario, I will not be surprised if the A320NEO will become the A360, an all new design. It can be similar to what transpired with the A350, that became the A350XWB, but now just called the A350. Airbus has at least 2 years to change its mind.
