While not announced onstage during Wednesday's iPhone event, Apple has quietly updated its iPad lineup specifications with storage buffs for iPad Air 2 and iPad mini 4, and price drops for the top-of-the-line 9.7- and 12.9-inch iPad Pro models.

The changes were noted on Apple's dedicated iPad webpage shortly after CEO Tim Cook closed today's event, which itself was packed with announcements regarding new iPhones, Apple Watch models, AirPods wireless headphones and more.

As seen in the comparison chart above, Apple is bumping the base storage capacity of iPad Air 2 and iPad mini 4 up from to 32GB, while at the same time eliminating the 64GB option. Configuration options are now limited to 32GB and 128GB. The change does not affect pricing, meaning customers get twice as much storage for their dollar.

Apple did, however, modify the price structure of its iPad Pro series. Only certain configurations benefit from the price drop, starting with a $50 reduction for both Wi-Fi and Wi-Fi + Cellular iterations of the 128GB 9.7-inch iPad Pro. The 256GB versions get a more substantial price cut of $100.

Apple's largest slate, the 12.9-inch iPad Pro, gets the same treatment as its smaller sibling. Prices of both Wi-Fi and Wi-Fi + Cellular models with 128GB of storage are reduced by $50, while maxed out 256GB configurations shed $100 off previous list pricing.
