It may be that they DO actually have some talented engineers and some interesting IP (such as a much better engine design) but were hoping to also generate additional revenue or get bought out by a bigger company. The fact that we are also seeing lots of companies come out with smaller turbojet engines (made for retrofitting older small planes that run on regular style ICE engines) makes me wonder if material science or other advancements have gotten us to the point where we are going to see some big improvements in turbojet and turbofans.
