Get ready for another October surprise.

For MacBook users,Karen Foster Archives it'll probably be a pleasant surprise, since Apple just sent invitations to an event on Oct. 27. Although, per usual, the invites didn't specify what the company has planned, all rumors point to a refresh of most of Apple's MacBook computers.

The event will take place at Apple's Cupertino campus, and it's scheduled to begin 10 a.m. PST. The invite says only, "Hello again," followed by a few brief instructions.

While that's not much to go on, there have been reports, from multiple sources, that Apple is set to announce a whole lot of new Mac computers; new versions of the MacBook Pro, iMac and Mac Pro all look likely. Additionally, the MacBook Air — Apple's entry-level laptop — may be revamped or phased out entirely. Even absent the reports, most of Apple's Macs are in dire need of a refresh, with some models not getting so much as a processor upgrade in years. (The only exception is the ultra-thin MacBook, which was upgraded in the spring.)

The most exciting rumor is that the new MacBook Pro could see a big design change: The row of function keys might be replaced with an OLED touch pad. The function and iconography on those keys could then presumably change depending on the active app; it would also be customizable.

At the same time, Apple's whole line will certainly get a processor upgrade. The new Macs could even be some of the first computers to come with Intel's seventh-generation Core processors (AKA Kaby Lake), though we'll at least see a jump to sixth-gen Core chips (Skylake).

And what else will be on deck? We may get the first official data (or at least hints) of how well the iPhone 7 and iPhone 7 Plus are selling, as well as iOS adoption. The iPhone 7 Plus may finally get Portrait mode in an update to iOS 10. And there's a chance the iPad Air 2 (now two years old) could get an incremental refresh.
