So Macedonia has closed its borders for migrants from the South, meaning that about 100k people are now stuck in Greece - a situation neither they nor Greece want. There are other ways, though (according to this German-language article on SPIEGEL Online: http://www.spiegel.de/politik/ausland/fluechtlinge-die-neuen-routen-der-schleuser-a-1079341.html): 1) They can pay 2500 Euros and will be smuggled to Southern Italy in a container, on ferries and ships from Piraeus. 2) They can cross the border to Albania and take a boat to Italy, something that thousands of Albanians did in the early 1990s. 3) They can take the land route via Albania, Montenegro, Bosnia-Herzegowina, Croatia and Slovenia. It is a pretty dangerous path due to land mines, but traffickers will likely re-open this pathway. 4) The Greece - Albania - Kosovo - Serbia route - this is one with high political explosiveness and a lot of conflict potential. The Kosovo is not officially recognized by Serbia - but if they wanted to stop an influx of migrants and refugees, they would have to build a fence, which would basically imply recognition of Kosovo. 5) The route via Bulgaria and then further on to Serbia or Romania. This route was pretty unpopular so far due to the brutal Bulgarian police - but border protection is rather weak. This may change, though, as Serbia has called upon Bulgaria to tighten its Western border controls and the military is now assisting police in securing the border. 6) The Black Sea route. Instead of bringing the refugees through the Mediterrenean, where NATO is going to be active, traffickers could bring people from Northern Turkey to Romania or Bulgaria. The options are many, and the potential for conflict is endless.
