When will 13'' retina MBA be out?

[riveting]

I was waiting for the 13 retina MBA but got disappointed to hear about rMBP. Well of course rMBP is a fantastic machine, it is just I don't want to spend $2000 on a laptop no matter how good it is and I prefer the small footprint from the air.
I could have ordered the 2011 MBA nearly a year ago, now the 2012 MBA is out, but I fail to see any significant difference. I would have jumped it if the 2012 MBA comes with an IPS screen (even without retina resolution).

When will the 13 retina MBA likely to be out. I have now a few choice, either running my old dell vostro laptop with P8400 processor (still running strong) or buy a new 2012 MBA or a refurbished 2011 MBA to save some money. Still debating, if I got a MBA, I might be able to sell my ipad to recoupe some money, but I would definitely miss the ipad IPS retina screen.

The 13" MBPR will probably be released before the Retina display is brought to the Air. You could be looking at a Retina Air, but at WWDC '13.

probably a while before the airs get retina b.c it would kinda make them not an air since the battery will have to be bigger
