Talk about cluttering up an already cluttered product lineup.
Keep.
It.
Simple.
Have Apple learnt anything from Steve circa 1997?
I'd like to think they are actually trying to simplify the product lineup (I hope at least). Everything at the moment is either a pro, air or mini. 'Air' doesn't make sense when the 'Pro' is just as small and light. Having two 9.7" models doesn't make sense, and the Air and Mini being the same price doesn't make sense (who the hell is going to buy a mini?). I'm hoping the new product line will look something like this:
2016:
12.9" iPad Pro $799
9.7" iPad Pro $599
9.7" iPad Air 2 $399
7.9" iPad Mini 4 $399
7.9" iPad Mini 2 $269
2017:
12.9" iPad Pro $799
10.1" iPad Pro $599
9.7" iPad $399
7.9" iPad Mini $299
Pro Models: A10X chip, Larger screens, Smart connecter and pencil support, specific features in iOS 11 (pop out apps similar to macOS (not just video), visible filesystem
Other Models: Smaller and cheaper, less Powerful, last generation experience
Come 2018 they will update the 12.9" Pro with a smaller bezel to 13.3" (maybe even keep the same screen size and make it smaller), pretty much what they are doing to the smaller version this year, they will cut the mini, and bring in an updated 9.7" to keep around. This way they keep their 'classic' size, and the product line reflects the macs (MacBook, MacBook Pro 2 sizes). It also reflects their change of direction, focusing on enterprise and on creating a legitimate computer replacement in the form of a tablet.
2018:
13.3" iPad Pro $799
10.1" iPad Pro $599
9.7" iPad $399
