According to Barclays analysts citing Asian supply chain sources Apple plans to launch 3 iPad Pro models on March 2017-- refreshed versions of the 9.7- and 12.9-inch models, and a bezel-free 10.9-inch version.
As detailed in a research note obtained by MacRumors, the bezel-free design allows the 10.9-inch iPad Pro to be the same physical size as the current 9.7-inch tablet, meaning it has an edge-to-edge design and and possibly no Home button. Speaking of the smaller iPad Pro, the analysts add the 9.7-inch model will be relegated to "low-cost" status together with the 7.9-inch iPad mini, a device not getting a 2017 refresh.
All three iPad Pro models should feature quad microphones and retain the 3.5mm headphone jack, while the 12.9-inch model reportedly gets the 12MP rear-facing iSight camera and True Tone flash found in the 9.7-inch model. Previous rumours from Japanese blog Mac Otakara say the 12.9-inch iPad Pro should also feature a True Tone display armed with four-channel ambient light sensors able to adjust colour and intensity according to the surrounding environment.
Customers wanting more "revolutionary" changes to the iPad will have to wait, though-- OLED displays will only hit the Apple tablet come 2018.
