To me the most promising aspect seems to be async-await on Android. It'd eliminate so much frustration in developing for that platform. In general, after bouncing between various desktop, mobile, and web-based technologies, I've come to the conclusion that any binding/event-based GUI system needs some sort of async-await or futures support to be truly workable. Otherwise, performing background tasks without locking up the UI involves way too much boilerplate and tends to blow up the architectural complexity of the application.
