Apple quietly did some changes to the pricing and storage of the iPads after their event today. The iPad Air 2, mini 4, and mini 2 all got an increase from a base of 16GB to 32GB. The iPad Pros also got a price reduction. The 128GB and 256GB Wi-Fi and cellular models all got a price cut. The 128GB models saw a $50 price drop where the 256GB models got a $100 reduction.
These prices are in effect right now. There is nothing new with these devices. Just the base storage and the price on some of them.
