When can we expect (or how long it will take) to get the response per E-mail from Blizzard that we are in (or not) the WOW Beta test? How long did it take for the US Beta to get the E-mail response?
The sign up is three weeks long. For the American beta, you were only contacted if you got in. So, you only will know if you get in, not if you don't. There are people who are still receiving e-mails for beta, so don't despair if you do not get in first thing. You may still get in at another time.
