I've been keeping up with this conflict for over 2 years. Here is the best up to date map of the conflict I use: https://mideast.liveuamap.com/
What I think is more likely to happen, than it used to be, is the breakout of a regional war. Currently this is a proxy battle between 2 different sides. One side is the US, Saudi, Israel, the Islamist gangs, and NATO to an extent. The other side is Russia, Iran, Bath Party Syria and Iraq, and China somewhat.
Recently the Kurdish people have called for independence: https://www.nytimes.com/2017/09/23/world/middleeast/turkey-kurds-independence-referendum.html
Turkey is currently massing troops and holding military exercises on the border with Kurdistan, ready to take over key strategic lands. Turkey has also shifted away from NATO and sided more with Syria and Russia, at least in terms of keeping the Kurdish people down.
It's unclear what will happen to the power dynamics of the region after ISIS is wiped out. It's possible that there is a clampdown and eerie peace. Or it is possible for a larger conflict to explode. We'll see.
