Apple’s big product release event earlier this week was missing any updates on new MacBooks, but new versions of the tech giant’s popular laptops could still be right around the corner.

That’s according to tech website DigiTimes, which reported Tuesday that Apple AAPL will start shipping new “ultra-thin” 13-inch and 15-inch MacBooks before the end of the second quarter. That could mean an announcement of the new laptops at Apple’s annual Worldwide Developers Conference, which typically takes place in mid-June.

DigiTimes also reports that the new laptops will “share a design similar to the existing 12-inch MacBook” while coming in even thinner than the company’s MacBook Air. As MacRumors points out, Apple has never released a 15-inch MacBook Air and a redesigned version of that product (possibly including Retina display) would likely be considered something of a surprise to analysts.

Fortune‘s roundup of analysts’ reactions to Monday’s “Let Us Loop You In” media event mentioned the lack of any new MacBook announcements, though Sterne Agee’s Rob Cihra did note that an update could come in time for WWDC as the company is in the process of outfitting its MacBook lineup with Intel’s INTC Skylake processors.

At its event on Monday, Apple did announce a new iPhone that returns to the 4-inch screen, as well as a 9.7-inch iPad and a cheaper Apple Watch.
