Apple’s iOS 7 will arrive “on time,” according to a couple of well-placed sources following a report from Bloomberg this morning that suggests it was risking delays in the face of major software changes. Apple blogger and noted beard-wearer Jim Dalrymple gave one of his famous one-word confirms today on his blog, agreeing with a source which told AllThingsD that while Apple has had to shift engineering resources away from OS X to iOS to make sure things proceed on schedule, the update will arrive on time. Apple says on its WWDC landing page that we’ll see “what’s next in iOS and OS X,” but it hasn’t spelled out that we’ll see new versions of either its Mac desktop OS, or the mobile platform that powers iPhones and iPads. Still, the focus at WWDC is on software, and it’s more than reasonable to expect given the teaser on the information page as well as references to the future of iOS and OS X made in the official press release noting when tickets for WWDC would go on sale this year.
