Just got one too! I tried right at launch time, eventually got locked out for too many purchase attempts while their servers were failing and had to go back to work. On whim, tried again 15 minutes ago and was able to get one shipping in 2~4 weeks. Soooo happy!
Same here. I was closing steam, figured it wasn't my lucky day after the out of stock message, and just refreshed the order out of habit and it went sailing through!
