The 12.9-inch iPad Pro will get similar upgrades that will see it come with True Tone Display with DCI-P3 color gamut support, 12MP iSight camera, and quad microphones. The other two iPad Pro variants will also feature quad microphones. Unlike the iPhone 7 and iPhone 7 Plus, the new iPad Pro variants will continue to feature a 3.5mm audio jack.
KGI analyst Kuo has also predicted that Apple will be refreshing its iPad lineup in early 2017. He also predicts that the 9.7-inch iPad will see its display size being bumped but to 10.5-inches instead of 10.1-inches as Mac Otakara predicts. The tablet will make use of a new display technology that will make zooming, panning, and UI interactions smoother on it.
