Apple pushing Jony Ive and Craig Federighi into the limelight

So Apple granted executive interviews with Bloomberg Businessweek and USA Today. Aside from Tim Cook, Jony Ive and Craig Federighi were the only other execs interviewed. One thing is clear, the two guys really seem to get along. Tim Cook said they "complete each other sentences". So is Apple pushing these two because of iOS 7? Or to push their whole collaboration meme? Or is it signaling these two are really running the show at Apple and one of them is the heir apparent to Cook?
