Here are pictures of the finalists, both taken during the semi-finals, I think. JulyZerg is on the left, doing a victory sign, and Reach is at the right, wiping off sweat between the games versus Silent_Control.
FakeSteve over at TeamLiquid.net has managed to get an interview with JulyZerg, where they talk a lot about the upcoming final, and about the semifinal versus iloveoov. It was translated by Junhong, and Legionnaire helped FakeSteve to settle it up. In the interview you get to know that JulyZerg's real name is Park Sung Jun and that he is 19 years old.
As a matter of fact, FakeSteve is doing another interview with JulyZerg after the OnGameNet finals, and he wants you to write questions for him to ask. You can find the thread » here. Who's going to win this? The rising Zerg star JulyZerg, or the cool Protoss Reach? Only time will tell. Last OnGameNet was won by Nal_rA, another Protoss player. Will Reach do what Nal_rA did, or will JulyZerg win this? I'll keep you posted!
