Microsoft might be getting ready to drop Kaby Lake CPUs into its Surface Book and Surface Pro 4 devices, if a change to Amazon's listings is anything to go on. The company has an event set for October 26, where experts are expecting it to show off a Surface-branded All-In-One system alongside some news on where Windows 10 is headed. Windows Central spotted a change on Amazon that shows all listings for the Surface Book and Surface Pro 4 now tagged with "(OLD VERSION)," and we wouldn't be surprised to see a refresh announced at the event.
It's important to note that these devices aren't expected to be called Surface Book 2 and Surface Pro 5. A source told Windows Central that Microsoft is talking about a Kaby Lake Surface Book that is otherwise identical to the current edition. A Kaby Lake upgrade would bring a small power boost and improved battery life to the device, and bring it up to current specs until Microsoft unveils a more substantial update.
Take this with a full-sized grain of salt at this point, but with Microsoft's event less than two weeks out, we'll know one way or the other soon.
