I haven't got the email yet, but I just checked the Apple store site and my Quad shipped today! I know some of you are waiting too, so I thought I'd give you some details, in case you're as impatient as me.
I ordered a CTO Quad (1GB RAM, 500GB HDD, AirPort Extreme + Bluetooth, 6600) as soon as the store came back up after the announcement. I'm in NYC so it looks like post-announcement Quad orders are shipping to the US now too. It's supposed to arrive at 3pm tomorrow (Tues. 11/14). I'll be glad to run any benchmarks or answer any questions tomorrow night.
