Apple is working on updates across its entire product line for the second half of 2018, according to a new investor's note shared by reliable Apple analyst Ming-Chi Kuo, with refreshes expected for iPhone, iPad,
Mac mini 
, MacBook Pro, iMac, and Apple Watch.
- iPad - Apple is working on two new 11 and 12.9-inch models that are equipped with a full-screen design and no Home button, with Apple to replace Touch ID with Face ID.
- Mac mini - Processor upgrades expected.
Kuo doesn't provide details on when we might see refreshes to Apple's other product lines, but the company could be planning to launch all of the refreshes at its annual September event.
In the past, Apple has also held separate October events when there is a heavy fall product lineup to unveil, so Macs and iPads could come in that month.
