I think we're likely to see an 11" MBA weigh in at about $1399, with the 13" MBA at $1599, to keep Apple's pricing structure all in line. That's reasonable, I think, if they're going to all SSD (even if it's built-in, that doesn't mean they'll drop the price compared to having a standard HDD). Best case scenario, maybe $1299 for the 11". That said, I was way off on the iPad pricing, and Apple's surprised me in other ways recently too, so I'm not going to rule out the possibility of a $999 11" MBA. I don't think it's likely though.
