There's a lot of people in Southeast Asia. More than 25 million, which is roughly the population of Australia combined with New Zealand. But as with most sports, we tend to punch above our international weight - and in the first official Starcraft 2 Battle.net competition, half of the entrants are from Australia/New Zealand.
Blizzard is using the Battle.net ladders to determine who gets entry, and six out of the sixteen players are Australian, with two New Zealanders. A full list of entrants and rules can be found here.
The competition will play out this weekend, and there'll be a live stream with commentary on the Archaic eSports site, here and here. The first round will be played tomorrow night at 9:30pm, the second begins Saturday at 3pm, and the final on Sunday at 3pm. It's not official, but we expect replays to be available afterwards as well.
Surprisingly, only 3 of the competitors are choosing Terran (Protoss being more favoured), despite Terrans receiving the most nerfs in the upcoming patch.
Immunity representative Andy "GlaDe" Pender will also be playing, whose mastery of Zerg vs Terran (his first matchup) will hopefully be enough to overcome the current high-level strategic trend of Reaper Rushing.
