novas bind is genuinely insane and they have good stuff on every map ive seen them play. they are a bit rough around the edges sometimes but the individuals often make up for that. traces map pool has always been their problem so i think their game against edg will tell you a lot about if nova will beat trace but they are seriously contenders for bangkok if they keep their form

Imo it's most difficult to predict pacific and the second Chinese team. FPX are pretty mid right now but when all of their players are online they look like the best mechanical team in the region. But I'll go with Trace because they've been improving a lot. NOVA and BLG are also possibilities.
