According to Chinese social media posts, macOS 10.16 will be called "Big Sur," and both it and iOS 14 will see big user interface redesigns.
Iconography supplied by Apple for the 2020 WWDC
Expected to be announced at WWDC later on Monday, macOS 10.16 "Big Sur" will not just get a redesigned user interface. Allegedly, a "huge update" is coming to Safari as well, but no details were shared beyond that.

The big changes said to be coming to iOS 14 include a redesigned homepage, a new widget technology, and a changed app alignment. The most profound change to how the iPhone presents itself, however, is incoming calls not being full screen, popping the user out of the existing app.

As they do every WWDC, Apple's other operating systems will see refreshes as well. Apple's tvOS 14 is said to "monitor the HomeKit" but perhaps not see major changes.

Furthermore, the @l0vetodream account addresses the "Year of A14," a reference to the chip that will be in the "iPhone 12" later in 2020. It isn't clear specifically what this means, however.
As always, the leaker says very little, but l0vetodream has an increasingly strong reputation for correctly revealing future Apple products. The account's previous correct leaks include ones about iPads, including the addition of a LiDAR sensor that then appeared on the iPad Pro.
