Russia and Turkey will talk tough, but neither want escalation.

Russia also wants ISIS to be attacked (ISIS has actually threatened attacks on Russia more than any other country).

Russia will keep its aircraft further from the border. More anti aircraft missiles will be moved into Syria, by the US (supply to rebels) and the Russians. It will be harder for Russian aircraft to operate in Syria (rebels shot down a Russian helicopter trying to rescue the pilots). US-supplied anti tank missiles will make life harder for Russian-backed government forces on the ground. It may also be harder for the US, France, etc to bomb ISIS targets in Syria (if they overfly government controlled areas). This is a recipe for an increasing stalemate in Syria.
