I don't know what will be a trend for the 2017.
I'm pretty sure where, as UX, I will invest my time and effort to work with.
- different way to access web pages with a mobile device (eg facebook browser, twitter browser)
- devices with larger screens and different way to handle the "comfort tapping zone"
- new UIs for smart objects and a bunch of integrations with the existing ones
I don't agree with the post about the "rapid prototyping". In my experience the quality of the prototype is strictly related to the goal that you want to achieve. A lot depends on the audience, if they are able to understand a lo-fi proto and they can provide you a good feedback.
