Hmmm...they could send out beta test CDs like Blizzard does. But I don't think that would work. I beta tested the Diablo II expansion and that was Realm-only. After the test was over, the CD became useless. A beta test CD of a single player game would be a little too valuable just to send to people (can you say pirate?). Plus, from what I've read of game developing, in house testing seems to be better because you get feedback quicker.
By the way, where would the game be beta tested?
