First, consider the fundamental reason for using twin engines. It is primarily because existing turboshaft engine designs were not perceived as having an acceptable level of reliability for the given applications. On the other hand, using a single larger turboshaft engine would give better fuel efficiency and much lower manufacturing cost.
The new generation of turboshaft engines are far more reliable than previous ones. So I think we'll see more new helo designs using a single engine instead of twin engines.
riff raff I am sure that you are ruled under FAA, come across the pond to see how things re looking and you will quickly realize that European agencies are not looking at thing in this way at all and so are Europeans manufacturers: we europeans love to make things very complicated and pragmatism isn't something that attract our laws makers trust me...
I only wish you were right, but me think we can only dream of it!
