For many years, upgraded MBA models have been released at Apple's WWDC. This year some of the rumors have pointed to a Q4 2014 release for a totally new ultra-thin 12" retina MBA. What do you expect to see at WWDC? If Apple upgrades the current 11" and 13" MBAs in any way would that squash any hopes of getting a completely new ultra-thin MBA? Could iOS 8 or the new OSX, introduced at WWDC hint that the new MBA will actually be ARM based?
