(Pocket-lint) - There's been a lot of talk of a refresh to Apple's iPad line-up recently, with more evidence appearing thanks to the iOS 12.2 beta code.

Buried within the code is reference to new iPads - thought to be an update to the iPad mini and iPad 9.7 - and it looks like they are going to miss-out on Apple's Face ID feature.

The information comes from Steve Troughton-Smith who has broken down the code to see what lurks within. In this case, it suggests four new iPad models (Wi-Fi and cellular versions of the iPad mini and 9.7) without Face ID.

Face ID is the feature that will use your face to unlock devices. It was introduced on the iPhone X in 2017 and ushered in a new method of interaction with Apple devices. Removing the home button also flushed out the older Touch ID system, a change that rolled into the iPad Pro in 2018 too.

Listing these devices without Face ID suggests that Apple is reserving it as a premium feature for its top devices, but it does mean that there will be new devices launched that support the older method of interaction, using a home button, rather than having a unified user interface across all devices moving forward. 

The code also suggests that there's an iPod touch update incoming, something that had been previously speculated. With new iPad models reportedly entering the EEC database, it's starting to suggest that we'll see an Apple event some time in Spring to launch new iPads.

We will keep you posted.
