A little surprised with the mini, but I am sure it will be a good model for a lot of people. I am only curious on whether or not they will retain the home button or move to the new design language and Face ID.
I suppose it depend on the price. If they go for a Standard iPad in a Mini body, I would guess not, simply due to margins. I think it would have to currently be an iPad Pro Mini to get the FaceID tech. But maybe in a year or two after costs of production come down, I could see FaceID making it into the Standard iPad line-up.
I'd be curious to know if Apple is updating the Mini more so for the general consumer or for Businesses & Education. Seems like I always see Minis in use for various small businesses and restaurants, and a Speech Language Pathologist in my district got a number of Minis (And the 2017 iPads) last school year through a grant to implement them as AAC (Augmentive & Alternative Communication) devices for students that need them.
