The OKC Apple Store just told me the same thing. They have the 13 inch MBA configured with the i7 chip, 8MB of RAM, and 512GB of flash storage. I am seriously considering going there this afternoon or tomorrow to pick one up. I have had a 2010 MBA with 4MB of RAM and 256GB of flash storage since it was released in October 2010. It has been the best computer I have ever owned, so am really looking to the doubling of memory and storage now available on the 2012 model.
