The images show that the design language will be similar to the 2nd Generation iPad Pros. It has the same style antenna lines, a headphone jack, presumably Lightning, and no camera flash. It also appears to have the lower-res camera that the current iPad (6th Generation) has, as there is no camera bump. Also, there are only 2 speakers.
The leaker claims that the iPad will feature the 2015 A9 chip. This is interesting, since Apple seems to have done away with the A9: no more iPhone 6S, iPhone SE, or iPad (5th Generation). However, its also possible that Apple is trying to get this iPad in the $200-$230 range to offer iPad access to even more people.
There is also no TrueDepth Camera System, so it’s safe to assume that this iPad will use Touch ID, just like the current Mini and regular iPads.
