After the implosion of the US Empire IS in Syria will disappear as they are financed by them. And also Erdogan will disappear when first the NATO implodes with the USA or before by the implosion of the EU. So after the first implosions Syria will improve and most of above implosions will happen this year. So the worst is already over.
I actually think that the war will become more complicated in Syria, Anyway let's see what will happen next.
