While Apple's WWDC 2018 keynote on June 4 should contain some important announcements, new MacBooks and iPads won't be among them, a report claimed on Thursday.

The company is crafting new models of the MacBook Pro and 12-inch MacBook, as well as a replacement for the MacBook Air, Bloomberg sources said, backing up some earlier rumors. But none of these are expected to ship until later in 2018, even though Apple last refreshed its MacBooks in the same month last year.

The sources added that updated iPad Pros with Face ID are also coming, but they'll likewise miss WWDC despite a prior refresh happening in June 2017.

Software announcements may include "iOS 12" upgrades like an unspecified "Digital Health" initiative, more control over notifications, and the introduction of "ARKit 2.0." The last item will allegedly enable multiplayer gaming in compatible apps.

Apple's rumored efforts at putting iOS apps on Macs may make an appearance, but that's uncertain.

When they do upgrade, at least some MacBooks are expected to shift to Intel's faster Coffee Lake processors, and could even adopt TrueDepth cameras to support Face ID. Upgrades to the Air are less certain, but the laptop is now badly outdated, lacking even a Retina display.
