Turkey doesn't want to lose all of the goodwill its been building up in the Arab world and Syria has an incentive to be loud and warmongering, as long as there is no actual war to speak of. I bet it'll end like the recent showdowns the Koreas had, with Syria playing the North and Turkey the South.
Considering Saudi Arabia's actively arming the rebels and Egypt is incredibly condemnatory towards Assad, I'm not sure how intervention would lose goodwill among the Arab world.
Easy. The Turks go in, kick Assad out, but reestablish along the coast an Alawite State (a la Northern Cypress) and keep troops there ostensibly to keep the peace.
