as Epic said in one of their stream “we understand the potentials of C# but we would not have anyone who would internally use it”.
I think that instead of improving the programmer experience they are trying to reduce the need of it through blueprint, any scripting talks is probably related to blueprints itself (maybe giving a base intellisense to a text-based version of blueprints).
Furtheremore I didn’t see any updates from the xamarin team and Microsoft is pretty much pushing Unity. There is also a new engine (now in beta) which is called Xenco that may became a valid alternative.
