We aren't planning to have one big beta invite tomorrow. Right now the beta primarily consists of the tournament teams, Dota1 beta testers, and other players that might compete in upcoming events. We will gradually give access to more and more players over the coming weeks and months. The Dota2 development process, like with Dota1, is focused on getting incremental player feedback to help us prioritize features and functionality in the game. There won't be an immediate million person invite all at once, but rather a gradual buildup as we develop new features and test various aspects of the game in order to to make it an enjoyable experience for an expanding player base.
Dota2 Info-Beta Update
Bueno por lo menos así corrigen cosas y escuchan a los beta-tester serios que buscan bugs etc... para que luego tengamos un producto más pulido que para eso está la beta. Pues toca esperar para que pillemos una.
