Well, no. The old strategy of adding Touch ID to the mini 3 and calling it a 4, adding a chip to the Air and calling it and Air 2 was killing sales. Most people are not going to spend hundreds of $ to update to essentially the same device. This year's crop of iPads is really the first "all new" line up since the Air and Mini 2.
The mini 4 received big upgrades: laminated display, increased color gamut, thinner chassis, A8, 2GB RAM. Consumers responded negatively and it did nothing except continue the slide in iPad sales.
The Air 2 was overpriced for what it offered.
The 2017 iPad ($329) isn't all new except for the price. I think it's pretty clear consumers are responding positively to the low price and 9.7" display.
