I've got mine today. There is another topic about it few inches below this topic Looks like most of the folks received their cards by now.
And to make it funny, I just received email from US Airways regarding my Gold card.

"We apologize for the delay in responding to your request and any inconvenience this may have caused.

Your Gold Preferred welcome kit and card should arrive within the next 2 weeks.

In the meantime, your Preferred status will print on your boarding passes so you can enjoy your benefits when you travel on US Airways or any Star Alliance carrier, including priority check-in and security lines (where available) and priority boarding.

Thank you for being a member of our Dividend Miles program. We look forward to assisting you with any future needs."
