Here's an interesting post from what looks like a site in Zaire wondering if Blizzard will ever bring World of Warcraft to South Africa. It's true -- we all take it for granted that here in North America and Europe, the game is available, but in many parts of the world, it's not. And apparently there's a market in a place like South Africa -- Blizzard says they have about five to seven thousand players down there already (we'd assume they're playing on EU or US servers), and that probably doesn't count any of the players on private servers, which could be as many as 20,000.
iGame is a division of an ISP called iBurst down there, and they say they're prepared to run an official server (within 24 hours' notice!) if Blizzard gives the OK, but Blizzard has told them that they need at least 40,000 players in the area to make it worth running an official server.
There's another option called a "peering" server, which apparently does hook up to Blizzard's servers, but uses local connections and networks to make things a little faster. But again, Blizzard needs to assent to that, and it seems like they're hesitant at the moment.
Oceanic realms have had issues for a long time, but at least the players there do have a chunk of servers dedicated to them. Are there any other major places in the world that don't have official WoW support yet? South America? India?
