Astralis vs Natus Vincere
It will be an amazing match, Astralis it's the second better team at this moment, Navi #4. Both teams have an excellent map pool, and the last matches between them were always tough. H2H 21-20 to Astralis but NAVI won the last two series (4-1), including one in this week, BUT Astralis always grows in Semi and Finals. It's a 55-45 to Astralis IMO. Each is able to will win any map of choice, probably Inferno and Dust2 or Train. I expect 3 tough maps.
