Tim Cook is set to take the stage for the WWDC 2012 keynote to reveal iOS 6, Mountain Lion, new Macs, and possibly more. Apple will surely make the video available later today for all, but if you want some hints as to what he'll be talking about this morning, check out his interview from the D10 conference. Tim talked with Walt Mossberg and Kara Swisher for over an hour about Apple products and strategies, and leaves some interesting hints by what he says--and what he doesn't say. Full video after the break.
