Well, everyone else who bought the beta that's said anything here bought it before the beta release date, so they all got the links a few days ago. I'm not sure how much the person running the NeoPwn v2 project is paying attention, so he may not get around to sending you links for a while.

But, basic answer: We don't know, because everyone else paid in advance of the 'release' date, so how quickly they got their links/emails doesn't necessarily reflect how quickly you'll get yours.
