Unless you are keen to help with testing and won't get phazed when it all turns to custard then you are fine to buy it. But really, waiting a couple of weeks isn't too bad - and beta is full of bugs at this point. I mean FULL of bugs! For me it is unplayable because of the audio issues, but then, I am an audiophile so it is really important to me. The eye candy is fine and all but you'll see it all in a couple of weeks anyway. I'd hate for you to spend the money and then when the 18th (or whatever) rolls around you are left questioning yourself - "why did I bother?"
