One of the features that is returning from Diablo 2 to Diablo 3 is the followers you can recruit. They seem to be fully customizable and have different classes to pick from.
I know the announcement of this class is about half a year old but it is probably what il end up playing when the game is released. you cant tell me that demon hunters wont be awesome after watching the trailer!
Beta is supposed to begin this summer / fall so make sure to log into batt.net and sign up for it!
The 3rd quarter reference in the earnings call today was a calendar quarter, meaning that we're aiming to launch the Diablo III beta between July 1st and September 30th. Keep in mind that it's our current goal, and of course that can change as development continues.
