http://www.engadget.com/2015/03/05/wsj-talks-up-retina-display-macbook-air/ The WSJ is rarely wrong about Apple's upcoming plans, if ever. I think it's considered common knowledge by now that Apple does strategic leaks to them. So now we know that there will be a 12" MBA with a high-res screen that ships in the 2nd quarter (April, May, June). Based on the leaked photos of the rMBA lid, the dimensions look to be 88-89% of the MBP in terms of width and depth, so, 11" wide and 7.67" deep. In other words, it will actually be about 5% smaller than the current 11" MBA. Mostly more narrow. So expect a keyboard with less overhang on the sides. I'm interested to see how they do this because with the current design it doesn't seem possible to have USB ports on the sides without keyboard overhang.
