Plans to launch a new MacBook Air and iLife '11 have been virtually confirmed this morning both by unofficial leaks and by Apple itself. The company's discussion forums already have placeholder categories for the "MBA" notebook as well as iMovie '11, GarageBand '11 and iPhoto '11. Polish site Spidersweb, who first found the leaks, also discovered a mystery "Reserved 10 20" category that could represent a new app or piece of hardware.
