Apple is allegedly making a larger iPad, the Apple iPad Pro. The larger iPad will be 12.2 inches large and with a Retina Display. Rumors also suggest that it might run both the iOS and OS X Yosemite. This might well be a hybrid- a tablet and a laptop. If they are able to deliver that, they will probably blow good Windows competition in the market.
Apple iPad Pro might also mean that Apple wants to put a full stop on the production of Apple iPad Mini range or atleast halt it for a while. This might explain why Mini 3 was not even the slightest update over the iPad Mini 2. Let us hope what Apple has in store for us is what exactly what we think they have- a hybrid + iPad running both iOS and OS X Yosemite.
