It is going to be interesting, even thou I dont see a clear vision for future of Apple.
1.- Huawei the fastes growing company have several issues to solve in EU and US
2.- The reaction for China (to apple) might be similar, there are legal issues incluiding qualcom, and there are chances China might block iphone (at least previous verisions) That is what you can see in several news. Apple vs. Qualcomm Legal Battle: Everything You Need to Know | Digital Trends
3.- I dont know if the growth of Apple in previous years was due increasing sells or increasing price (or both)
4.- This year it looks like the increase in price can´t compensate de decrease in sells.
So in my perspective, legal issues, block in china one of the greater markets, decrease in sells, (personal view) lack of innovation, this wont be a good year for apple.
