According to a local paper, one of the Friuli stages should go from Grado to Gorizia (I assume it is the one that was supposed to end in Cormons, which is quite close to Gorizia). A finish at the Tre Cime di Lavaredo is also rumored. That would most likely rule out Cortina, but since the Tre Cime are quite close to Cortina, it does not change anything in terms of what we know about the structure of the Giro (which is to say, not much at this point).
The final stage is still between Verona and Milan (which in all probability does not mean that Vegni is still deciding between the two, only that there are conflicting rumors).
