I'm confused by people that keep saying this. Do you think they're not going to get to us until a week before launch and say "oh well! hope things work out for you guys"?
Cataclysm isn't expected until the earliest November. It's just going to be August tomorrow. That means that, at the very least, there's still 3 months of testing to do. Even if they don't get to us until September, that's two whole months of testing. If you're trying to say that two months isn't enough, then I wonder what you as a beta tester are doing in the first place.
There's loads of time. They'll get to us when they get to us, and we'll have plenty of time to work out all the kinks and bugs before launch. Patience. Search for it on eBay and get as much as you can buy for cheap. Please.
