Greek wine: rising and falling trends for 2018

The beginning of each year is the time when predictions are a common thing among wine professionals. I generally avoid making prognoses, but occasionally I enjoy projecting to the future, albeit with calculated risk. If one doesn't risk, at least a little, nothing can be accomplished; and since Greek wine is an adventure, it involves a certain degree of uncertainty. 

At least, this is how I see things. Whether I am right or not does not change the fact that some questions need to be posed. For example, does Santorini stand alone, and what could be the next big thing (if there is one to be expected)? Are the wine styles changing, and which are the varieties one should be looking out for? I suspect that you see my point, so here we go for rising and falling trends for 2018 cornering styles and varieties.
