We've already seen some evidence that the foldable iPhone Ultra is on the way, thanks to code references in the iOS 27 beta, but there may be more hints already out there. According to Mark Gurman at Bloomberg, there are a bunch of references to both the foldable iPhone and the touchscreen MacBook Ultra in their respective software betas.
It makes perfect sense that there would be some clues as to what these devices may have to offer. The duo will likely be released at some point over the next 12 months, with an expected fall launch for iPhone Ultra and an early 2027 appearance for MacBook Ultra. That means they'll be running on iOS 27 and macOS 27, respectively, both of which have just been released in beta form.
