From ANSA:

Troy was much bigger than what was believed until now, Ernst Pernicka, professor of Archeometry at the University of Tuebingen and in charge of the excavations under way in Turkey, affirms. While the scholars believed for long time that the legendary city spans on a surface of at most 27 hectares, in fact Troy was located on a surface of 35 hectares, Pernicka told the German media. The continuation of a defensive trench from the Bronze Age was recently discovered by the archaeologists and it allowed evaluating unequivocally the real expansion of Troy.

The German coverage (if I'm reading it correctly) says much the same thing but also seems to hint that funding for the excavation is running out ... see, e.g., Kolnische Rundschau and FAZ ...
