We seem to be optimists here, hehe. I'm guessing MacBook Air/MacBook thingy (either, not both, maybe a thing to replace both), spec-bumping MacBook Pro, and sneak peek at a new desktop, whether it be a new iMac (Doubt it), a new Mac mini (maybe but don't think so - more likely they'll kill it), or what I do think; Them showing us an early taste of the 2019 Mac Pro. As I said though - Optimist.
The original MacBook Air only had 1 USB port, but had another added in an update. I hope the same happens to the MacBook. The Air also saw a massive price drop in an update, which would be nice if it happens to the MacBook, but would probably mean the end of the Air.
I had been expecting a preview of the new Mac Pro ready for a release next year, but that was until they recently said it wouldn’t be out until next year. They wouldn’t have done that if there was a preview coming.
Maybe some spec bumps.
An off-the-wall idea, ARM co-processors in all Macs for new security features, including biometrics. Or just a standalone fingerprint sensor.
