I ordered when it was in stock, and got a confirmation email.  They contacted me later to say it's out of stock.
I am guessing other people will get cancellations too

There are about 19 listings (one is for a used).  Some listing are for 2 cards.  So there are about 20-30 of them available on eBay... Not a whole lot...
They are selling at $1,050 -$1,100 on average...

There is a reason why they are so popular with miners, even experienced ones: It conserves PCI-e space.

It's practically 4 5770's worth of hashing power in 1 card. This means if you use extender cables you can use up to 4 of these for a 3.2gh/s rig.

Sure you can buy cheaper cards, but with that comes the fact you also need to build an entire system around them:
Your amount of required PSU's, motherboards, CPU's, RAM sticks and casing will increase, so you might not end up saving that much.
