Developer Stephen Troughton-Smith discovered references to four new ones iPad models, starting from iPad 11.1 up iPad 11.4, two of which are WiFi, and two of them are mobile. These model numbers do not correspond to any known iPad models.
Troughton-Smith speculated that iPad the model numbers may be new iPad mini devices, which will be in line with rumors suggesting that the new iPad mini 5 is in operation. According to Troughton-Smith, none of iPads has a face to identify, which is what you would expect as a new one iPad mini will most likely be positioned as an acceptable, lower device.
There is also a reference for "iPod 9.1", which does not match any known iPod touch devices, which indicates that it is a new model of the next generation. The current sixth generation iPod touch is "iPod 7.1" for reference. The iPod is listed in iOS 12.2 does not appear to have a face ID or a Touch ID, therefore it is not clear if something is missing or there is a design with none of these features.
Previous rumors really suggested that Apple is working on the seventh generation iPod touch, and iPad mini 5, and a new version at a lower price of 9.7 inches iPad, which can actually be upgraded to 10 inches in the next iteration.
In theory, iOS 12.2 references four new iPads in WiFi & Mobile variants (maybe mini, and 9.7??), All without a face ID and (seventh gay?) iPod touch with no Touch ID or person identification number pic.twitter.com/xiJN6kmmTe

Apple earlier this week registered seven iPads with the Eurasian Economic Commission, and at least some of them may be the four iPad models Troughton-Smith revealed in iOS 12.2. The numbers of these models include A2123, A2124, A2126, A2153, A2154, A2133 and A2152.
First we began to hear about Apple's work on refreshed iPad mini at the end of 2018, and since then, chatter has risen. Rumors proposed a new fifth generation iPad mini will be released in the first half of 2019, with signs appearing in iOS 12.2 and the Eurasian database (where Apple needs to register all new devices), this prediction sounds more and more precise.
There was mixed information about what to expect from iPad mini update. Case case suggested a vertical camera and quad speakers, but a picture of unissued iPad mini, which can be new iPad mini, there was an older A9 processor and a design that is similar to the fourth generation iPad mini.
We will need to wait for additional information to find out just what it is iPad mini will include but sounds more like the current 9.7 inches iPad from the iPad Pro. As for the launch date, it looks like it's potentially to come when iOS 12.2 is released, perhaps in late February or early March. The 7th generation is speculating iPod touch can be released at the same time.
Apple held events in March in recent years, so it would be no surprise to see another event in March 2019.
