Dude, hold your horses - they just came out!
Realistically, they probably won't be appearing refurbished from Apple for at least several months - before that, you'll probably have better luck on eBay if you can find people who bought them and found they didn't want/need them.
But considering you're only going to save a couple of hundred bucks, is it really worth the wait? If you need it now you should buy it now. And if you're buying to a budget you should just get the refurbed rev B's - the performance difference is not enormous and they perform the same functions.
But, your decision of course... hope you're happy with whatever you choose to do 🙂
