I'm waiting on the local Sprint store to call me when they have more stock. Seems a little silly that stores aren't expecting any new shipments this week. At least thats what was told to me by the Sprint employee when I reserved my phone. I did stop at Best Buy and they told me they were hoping to get more in stock this week but didn't know anything for sure. If you are specifically waiting on gold, then good luck. From everything i've read, you won't see it for at least a few weeks.
The gold shortage seems strange given how much Apple highlighted it during the keynote. Unless the intial internet backlash was enough to cause them to reduce manufacturing of gold? That seems very unlikely however.
