We already reported that Apple is planning to announce three new iPads this year. The company is expected to announce a 9.7 iPad with an affordable price tag, a new 10.5 iPad and an upgraded 12.9 iPad Pro.
Sadly the products are still in planning with the 9.7 device expected to begin manufacturing in Q1 2017 and the other two in the second quarter. The delay is happening because the A10X chipsets for the bigger two devices are still in production and Apple is unlikely to do one-device announcements.
Since theres no mini version expected 9.7 iPad will become the entry-level device, targeted for educators, the 10.5 will oust the current 9.7 device while the 12.9 will simply be an upgraded Pro tablet.
