It seems that Apple will launch three new models of iPad Pro for the first half of 2017, including models up to 12.9 inches.
The 12.9 - inch model will have a screen that includes "True Tone" technology (like the current 9.7 - inch iPad Pro) using ambient light sensors advanced four - channel to automatically adapt the color and intensity of the screen to match the light in the environment.
The iPad Pro 12.9 "might also include the same 12-megapixel rear camera that the current model of 9.7 inches. Apple apparently also include a smaller 7.9 - inch model, which is the successor to the iPad mini 4 and bear an intelligent connector, screen "True Tone", four speakers and a rear 12 - megapixel iSight camera. The three new models of iPad Pro apparently keep the headphone jack of 3.5 mm.
