If the new 3rd generation Ryzen stuff ends up being as good as it looks, then I'd say we're in for a good year as far as mobile AMD hardware's concerned. There's a good chance that you have nothing to worry about as far as upgrade paths are considered.
I hope so, but my current laptop has a desktop-class Ryzen 7 1700 in it and their mobile offerings usually come with half as many cores, but I guess we'll see what Ryzen 3 has to offer.
