A couple of bits of DOTA 2 news turned up. The first is that Valve have announced that The International Dota 2 Championships 2012 will be held at PAX Prime in Seattle, which takes place from August 31st to September 2nd. Valve report that the event will entail "16 of the most elite Dota teams competing in a group stage, double elimination playoff format for a grand prize of $1 million."
The second bit is that PCG noticed the game is now moving ahead of Counter-Strike: Source, Call of Duty: Modern Warfare 3, and Skyrim on Steam's player stats. And it's still just in beta. Huge it is going to be. Yes.
