The filings do not offer significant information about these new iPads, except that they will run Apple's recently-launched iPadOS.
TechRadar speculates that these could be new iPad Pro devices, although one of them could also be a replacement for the entry-level 9.7-inch iPad, which was introduced back in March 2018.
However, since the iPad Pro received a new design less than a year ago, it is unlikely that these models would offer a change in design – it is more likely they will offer improved performance compared to previous models.
Some rumours have suggested that Apple's upcoming iPads will offer improved reception due to innovations in the devices' antennae.
