Something we keep hearing about is a bigger iPad, shifting from the 9.7-inch screen found on the full-sized iPad, to a 12.9-inch "iPad Pro". The latest report from KGI Securities analyst Ming-Chi Kuo is that Apple won't put it into mass production until Q2 2015.
Kuo says that Apple will use an oxide panel in the iPad Pro to hit a "high resolution, quick response, and high color saturation" and that it requires more time to make this happen for component yield and assembly. We don't know much else about the iPad Pro, apart from it having a bigger screen size - floating somewhere between 12.2 and 12.9 inches.
It should offer an A8X chip, Lighting connector, and hopefully something that differentiates it from the iPad and iPad Air.
