While I usually agree with you, Seoman, I think this time the OB might actually be within one or two days. While they do need time to sort through the remnants of the last closed beta and get set up for the next stress test, every day that they go without a beta is a day without constructive feedback and disappointed future customers; knowing Blizzard they wouldn't risk it for very long. I think that we have very good reason to be optimistic...
You're right, though, in the sense that the game itself may not go gold for quite awhile. But, as long as the OB comes soon, I don't really care. :P
