According to the Indian blog MySmartPrice, Apple has registered six new iPad models, in the Eurasian Economic Commission database which indicate that new iPads will be coming soon. China Times, and supply chain-focused website DigiTimes, have claimed Apple plans to launch an iPad mini 5 and a new entry-level iPad with a 10-inch display, replacing the existing 9.7-inch model.
The models that were added to the Eurasian database were models A2123, A2124, A2153, A2154, A2133, and A2152. These type of database filings give us an idea on when the devices will release which it may release in March, as Apple usually has an event during March. Last year, Apple announced the iPad (6th generation) during the March Education 2018 Event, so this also gives us an idea that these new iPads will release sometime in March.
