The iPad Air 4 could be one of the featured products alongside the Apple Watch 6 at Apple's "Time Flies" event tomorrow. But you may end up paying a premium for the upgrade.

@L0vetodream, who frequently speculates Apple is "$5X9.... X > 6." Combined with the user's earlier tweet about the iPad Air 4, the tweet suggests that the new iPad could be priced between $569 and $599. This would be a notable jump from the current iPad Air 3, which starts at $499.

However, there may be a silver lining to this price increase: in a separate tweet, L0vetodream suggests that Apple's new product will support fast charging. This may refer to the Apple Watch 6, but it is also possible that the new iPad Air will have enhanced charging to bring it in line with the latest iPhones. both the iPad Pro and the iPhone 11 series support charging up to 18W.

According to the latest leaks and rumors, the iPad Air 4 is expected to be redesigned to look much like Apple's higher-end iPad Pro tablet. In terms of specs, we can expect an A14X processor, USB-C charging, and compatibility with the latest Magic Keyboard.

However, the advanced LiDAR depth-sensing camera on the latest iPad Pro will likely have to live without. Some rumors point to the iPad Air 4 supporting Face ID for faster unlocking, while other rumors point to the Touch ID sensor being integrated into the power button to allow for thinner bezels.

There is only a short time left until we can see what the final iPad Air 4 will look like in the flesh. Apple's September 15 Time Flies event will begin at 10:00 AM PT (1:00 PM GMT).
