Apple Insider offers a highly in-depth preview & photos of known expected items for Apple’s major product Fall 2018 launch.  More complete announcements are planned for September 12, 2018 by Apple:

AppleInsider will be bringing you all of the facts and testing the rumors up to the September 12 date itself. Then of course on the day you’ll be able to follow every detail as Apple unveils it.  You can of course also watch Apple unveiling everything. As is now normal, the entire event is going to be streamed online and on Apple TV.  This time, though, it’s rumored that Apple will also stream the event via Twitter —but we’ll see about that part.
