Headlining the event should be a totally redesigned MacBook Pro, which has existed in its current form for a good four years now. Rumors point to a touch-capable OLED strip on the keyboard above the number row that can adapt to whatever app you're using. Touch ID might be making its way to the Mac for the first time, as well. Of course, the computers will likely be thinner and lighter and will probably see many of the innovations Apple first rolled out in the MacBook in 2015. The butterfly keyboard mechanism, tiered battery design and reliance on USB-C all seem likely to come on board at this point. We're hoping the MacBook Pro will be available in a variety of colors for the first time, too.
Beyond that, spec bumps for the iMac and MacBook Air seem like good bets, as does the inclusion of USB-C on those models as well. Looking beyond the Mac line, it's also possible the iPad will get some love. The iPad Air 2, while still a very capable tablet, is now two years old. And the 12.9-inch iPad Pro is just about a year old and lags behind the smaller iPad Pro in a few key ways. It wouldn't surprise us to see both of those devices get some updates.
Whatever Apple has to show off, we'll be there live to bring you all the news as it happens when the event starts at 10AM PT.
