The new iPad mini 6 features a new design similar to the iPad Air 4 and iPad Pro models. The tablet received its long-overdue design change and comes with Apple's new A15 Bionic chipset. The pre-orders for the iPad mini 6 opened right after its announcement with first orders arriving by September 24. However, if you pre-ordered the new iPad mini recently, chances are that you would have to wait till the second half of October.

If you ordered the new iPad mini 6 from Apple's Online Store, some earliest deliveries are now pushed from October 19 to November 2, according to Loop's Dark Mark. If you order the 64GB variant of the iPad mini 6 and WiFi only, the shipment is expected from 4 to 6 weeks from launch. Nonetheless, if you like the new Pink color, it will be available by the initial September 24 timeframe.
