2017 Mac Mini
Apple has not updated the Mac Mini in about two and a half years. This is the longest time between refreshes of the Mac Mini, leaving many users hoping for a 2017 Mac Mini release in the near future.
There is a chance that we will finally see Apple deliver a 2017 Mac Mini with new processors at a Spring or Fall event.
In January Intel announced new Kaby Lake processors that could be part of a 2017 Mac Mini update. Apple does seem content to leave the Mac lineup to stagnate, but with no 11-inch MacBook Pro, there may be a new purpose for an entry-level Mac that more people can afford.
One ray of hope is that Tim Cook told employees that there are "great desktops" coming from Apple.
It's tough to nail down a specific date for the new Mac Mini, but it would make sense at a Spring event, despite no major leaks.
