According to reliable sources cited by 9to5Mac’s Mark Gurman, Apple will focus heavily on OS X 10:10 at WWDC 2014.
As for the next version of the iOS, Gurman says that many key features of the operating system will be postponed in order to be perfected.
Previous reports have claimed that the iOS 8 will include new apps including Healthbook, an improved Maps app, a standalone iTunes Radio application, TextEdit and Preview apps, and others upgrades.
In addition, Apple is working on significant changes for iCloud, which will come later this year.
Gurman also notes Apple is working on both new hardware and new software for its TV update.
